Most architectures don't need to do anything special for the strict
seccomp syscall entries. Remove the redundant headers and reduce the
others.

v2:
- use Kbuild "generic-y" instead of explicit #include lines (sfr)

Lovely cleanup factor.

Just to make sure, are you sure the 32-bit details are identical 
across architectures?

For example some architectures did this:

While in yet another case you kept the syscall mappings:

It might all be correct, but it's not obvious to me.

Thanks,

I did "gcc -E -dM" style output comparisons on the architectures I had
compilers for, and the buildbot hasn't complained on any of the others
(though see the bottom of this email).

The asm-generic uses the same syscall numbers from both 64 and 32,
which matches most architectures, and those are the ones that had
their seccomp.h entirely eliminated.

Well, this was x86's split config that was consolidated into the file below:

The x86 change was the most complex as it removed a seccomp_32. and
seccomp_64.h file and merged into a single asm/seccomp.h to provide
overrides for the _32 #defines.

However, in looking at it now... I see some flip/flopping of
__NR_sigreturn and __NR_rt_sigreturn between some of the
architectures. Let me study that and send a v3. I think there are some
accidental changes on microblaze and powerpc.
