[PATCH] syscalls: update the syscall table to v5.12-rc7

Due to additional ABIs in main we can't do a simple backport or copy
of the syscall table so we are generating it directly in the
release-2.5 branch.

This patch also fixes the missing faccessat2() #defines in the
seccomp-syscalls.h header file.
