time.c: introduce do_timerfd_gettime and do_timerfd_settime

These are going to be used to implement parsers of timerfd_gettime64
and timerfd_settime64 syscalls.

* time.c (do_timerfd_settime, do_timerfd_gettime): New functions.
((SYS_FUNC(timerfd_settime)): Turn into a thin wrapper around
do_timerfd_settime.
((SYS_FUNC(timerfd_gettime)): Turn into a thin wrapper around
do_timerfd_gettime.
