x86/syscalls: Move compat syscall entry handling into syscalltbl.sh
Rather than duplicating the compat entry handling in all
consumers of syscalls_BITS.h, handle it directly in
syscalltbl.sh. Now we generate entries in syscalls_32.h like:
__SYSCALL_I386(5, sys_open)
__SYSCALL_I386(5, compat_sys_open)
and all of its consumers implicitly get the right entry point.
