initramfs: remove redundant dependency on BLK_DEV_INITRD
init/Kconfig includes usr/Kconfig inside the "if BLK_DEV_INITRD" ...
"endif" block:

init/Kconfig includes usr/Kconfig inside the "if BLK_DEV_INITRD" ...
"endif" block:
if BLK_DEV_INITRD
source "usr/Kconfig"
endif
Hence, all the defines in usr/Kconfig depend on BLK_DEV_INITRD.
Remove the redundant "depends on BLK_DEV_INITRD".

initramfs: rename gen_initramfs_list.sh to gen_initramfs.sh
The comments in usr/Makefile wrongly refer to the script name (twice).
Line 37:

initramfs: rename gen_initramfs_list.sh to gen_initramfs.sh
The comments in usr/Makefile wrongly refer to the script name (twice).
Line 37:
# The dependency list is generated by gen_initramfs.sh -l
Line 54:
# 4) Arguments to gen_initramfs.sh changes
There does not exist such a script.
I was going to fix the comments, but after some consideration, I thought
"gen_initramfs.sh" would be more suitable than "gen_initramfs_list.sh"
because it generates an initramfs image in the common usage.
The script generates a list that can be fed to gen_init_cpio only when
it is directly run without -o or -l option.

initramfs: replace klibcdirs in Makefile with FORCE
'klibcdirs' was added by commit d39a206bc35d ("kbuild: rebuild initramfs
if content of initramfs changes"). If this is just a matter of forcing
execution of the recipe line, we can replace it with FORCE.
The following code is currently useless:
$(deps_initramfs): klibcdirs
The original intent could be a hook for the klibc integration into the
kernel tree, but klibc is a separate project, which can be built
independently. Clean it up.

Since commit d2a99dbdade4 ("kbuild: update compile-test header list for

kbuild: move headers_check rule to usr/include/Makefile
Currently, some sanity checks for uapi headers are done by
scripts/headers_check.pl, which is wired up to the 'headers_check'
target in the top Makefile.
It is true compiling headers has better test coverage, but there
are still several headers excluded from the compile test. I like
to keep headers_check.pl for a while, but we can delete a lot of
code by moving the build rule to usr/include/Makefile.

kbuild: remove header compile test
There are both positive and negative options about this feature.
At first, I thought it was a good idea, but actually Linus stated a
negative opinion (https://lkml.org/lkml/2019/9/29/227). I admit it
is ugly and annoying.
The baseline I'd like to keep is the compile-test of uapi headers.
(Otherwise, kernel developers have no way to ensure the correctness
of the exported headers.)
I will maintain a small build rule in usr/include/Makefile.
Remove the other header test functionality.
