selftests/bpf: Check if the digest is refreshed after a file write
Verify that bpf_ima_inode_hash() returns a non-fresh digest after a file
write, and that bpf_ima_file_hash() returns a fresh digest. Verification is
done by requesting the digest from the bprm_creds_for_exec hook, called
before ima_bprm_check().

in validating both IMA and the usage of the ringbuffer in sleepable
programs.

bpf: Add a selftest for bpf_ima_inode_hash
The test does the following:
- Mounts a loopback filesystem and appends the IMA policy to measure
executions only on this file-system. Restricting the IMA policy to
a particular filesystem prevents a system-wide IMA policy change.
- Executes an executable copied to this loopback filesystem.
- Calls the bpf_ima_inode_hash in the bprm_committed_creds hook and
checks if the call succeeded and checks if a hash was calculated.
The test shells out to the added ima_setup.sh script as the setup is
better handled in a shell script and is more complicated to do in the
test program or even shelling out individual commands from C.
The list of required configs (i.e. IMA, SECURITYFS,
IMA_{WRITE,READ}_POLICY) for running this test are also updated.
