This registers the new fchmodat4 syscall in most places as nuber 434,
with alpha being the exception where it's 544.  I found all these sites
by grepping for fspick, which I assume has found me everything.

434 is now pidfd_open, the next free one is 436.

You missed arch/arm64/include/asm/unistd.h, which
contains __NR_compat_syscalls
