asm-generic: bugfix for asm/unistd.h

Multiple people reported a bug I introduced in asm-generic/unistd.h
in 4.20, this is the obvious bugfix to get glibc and others to
correctly build again on new architectures that no longer provide
the old fstatat64() family of system calls.

asm-generic: unistd.h: fixup broken macro include.

The broken macros make the glibc compile error. If there is no
__NR3264_fstat*, we should also removed related definitions.

Reported-by: Marcin Juszkiewicz <marcin.juszkiewicz@linaro.org>
Fixes: bf4b6a7d371e ("y2038: Remove stat64 family from default syscall set")
[arnd: Both Marcin and Guo provided this patch to fix up my clearly
       broken commit, I applied the version with the better changelog.]
