I can only speculate, that this was probably a copy/paste error that has been there for a long time. __NR_faccessat is (and was) defined as number 301. Given that 287 was never defined, it's save to
fix the table entry and set it to sys_ni_syscall.

unistd.h:
[...]
#define __NR_faccessat                          301
__SYSCALL(301, sys_faccessat, 4)
[...]

Thanks,
-Chris
