crypto: testmgr - Allow ecb(cipher_null) in FIPS mode

The cipher_null is not a real cipher, FIPS mode should not restrict its use.

It is used for several tests (for example in cryptsetup testsuite) and also
temporarily for reencryption of not yet encrypted device in cryptsetup-reencrypt tool.

Problem is easily reproducible with
cryptsetup benchmark -c null

crypto: testmgr - replace compression known answer test

Compression implementations might return valid outputs that
do not match what specified in the test vectors.
For this reason, the testmgr might report that a compression
implementation failed the test even if the data produced
by the compressor is correct.
This implements a decompress-and-verify test for acomp
compression tests rather than a known answer test.

crypto: testmgr - use calculated count for number of test vectors

When working on AES in CCM mode for ARM, my code passed the internal
tcrypt test before I had even bothered to implement the AES-192 and
AES-256 code paths, which is strange because the tcrypt does contain
AES-192 and AES-256 test vectors for CCM.

As it turned out, the define AES_CCM_ENC_TEST_VECTORS was out of sync
with the actual number of test vectors, causing only the AES-128 ones
to be executed.

So get rid of the defines, and wrap the test vector references in a
macro that calculates the number of vectors automatically.

The following test vector counts were out of sync with the respective
defines:

BF_CTR_ENC_TEST_VECTORS 2 -> 3
BF_CTR_DEC_TEST_VECTORS 2 -> 3
TF_CTR_ENC_TEST_VECTORS 2 -> 3
TF_CTR_DEC_TEST_VECTORS 2 -> 3
SERPENT_CTR_ENC_TEST_VECTORS 2 -> 3
SERPENT_CTR_DEC_TEST_VECTORS 2 -> 3
AES_CCM_ENC_TEST_VECTORS 8 -> 14
AES_CCM_DEC_TEST_VECTORS 7 -> 17
AES_CCM_4309_ENC_TEST_VECTORS 7 -> 23
AES_CCM_4309_DEC_TEST_VECTORS 10 -> 23
CAMELLIA_CTR_ENC_TEST_VECTORS 2 -> 3
CAMELLIA_CTR_DEC_TEST_VECTORS 2 -> 3

crypto: testmgr - Allocate only the required output size for hash tests

There are some hashes (e.g. sha224) that have some internal trickery
to make sure that only the correct number of output bytes are
generated. If something goes wrong, they could potentially overrun
the output buffer.

Make the test more robust by allocating only enough space for the
correct output size so that memory debugging will catch the error if
the output is overrun.

Tested by intentionally breaking sha224 to output all 256
internally-generated bits while running on KASAN.

The test vectors used for input are part of the kernel image. These
inputs are passed as a buffer to sg_init_one which eventually blows up
with BUG_ON(!virt_addr_valid(buf)). On arm64, virt_addr_valid returns
false for the kernel image since virt_to_page will not return the
correct page. Fix this by copying the input vectors to heap buffer
before setting up the scatterlist.

Commit 7e4c7f17cde2 ("crypto: testmgr - avoid overlap in chunked tests")
attempted to address a problem in the crypto testmgr code where chunked
test cases are copied to memory in a way that results in overlap.

However, the fix recreated the exact same issue for other chunked tests,
by putting IDX3 within 492 bytes of IDX1, which causes overlap if the
first chunk exceeds 492 bytes, which is the case for at least one of
the xts(aes) test cases.

So increase IDX3 by another 1000 bytes.
