busybox: fix time64 patch.

The syscall name was changed explicitly so compilation broke instead of
allowing programs using the raw syscall to use the time64 struct
timespec with a syscall expecting the old one.

Since we have modern glibc and musl, we can just force clock_gettime
usage.

The previous patch also broke y2038 support.

Not revbumping, since c085deae94 didn't
either.
