[LTP] [PATCH 1/2] lib: Add safe timerfd macros

Hmm, I'm not sure how useful is this. Generally the syscalls in libc
have single macro definition that is used everywhere to copy the error
from the errno variable. If that piece of code is buggy half of the test
in LTP would fail anyway.

I think that it's completely wrong to put kernel version comparsion to
the safe_macros. If the test needs specific kernel version it should be
either put into the tst_test structure of handled in the test setup.
