Kernel version specific __KPATCH_SYSCALL_DEFINEx macros were added to
kpatch-syscall.h for x86, but only single versions for other arches.
This works out for s390x, but not ppc64le for which kpatch-build support
goes back to kernel versions that require slightly different macros.
Reorder the __KPATCH_SYSCALL_DEFINEx macros to define the arch-specific
ones first (arch/.../include/asm/syscall_wrapper.h) and then fall back
to using generic ones (include/linux/syscalls.h versions).
Fixes: #1278
