Mike Frysinger f1639d8f51 timerfd: update flags decoding 
The current code only decodes TFD_TIMER_ABSTIME when the kernel has
a bunch of newer flags.  We have to handle fallbacks for all of them
since the kernel doesn't currently export things to userspace.

* time.c: Include fcntl.h for O_* defines.
(TFD_TIMER_ABSTIME): Move to xlat/timerfdflags.in.
* xlat/timerfdflags.in: Add more definitions.
