For !__ASSUME_TIME64_SYSCALLS there is no need to issue a 64-bit syscall
if the provided timeout fits in a 32-bit one. The 64-bit usage should
be rare since the timeout is a relative one.
Checked on i686-linux-gnu on a 4.15 kernel and on a 5.11 kernel
(with and without --enable-kernel=5.1) and on x86_64-linux-gnu.

There were following problems discovered for tst-timerfd test:
1. Do not set the struct itimerspec's it_interval tv_sec to 2 seconds.
After this change the timerfd will trigger only once (the it_value is
only set in this case).
2. The 'val1' variable (including the call to timerfd_gettime) is not
needed anymore, as it is just enough to read the struct itimerspec
after sleep. As a consequence the 'val2' has been renamed to 'val'.
3. After calling timerfd_gettime, the value of struct itimerspec time,
when timer is running, is the remaining time. In the case of this test
it would be less than 1 second.
As a result the TEST_COMPARE macro logic had to be adjusted.

This change adds new test to assess functionality of timerfd_*
functions.
It creates new timer (operates on its file descriptor) and checks
if time before and after sleep is between expected values.
