[PATCH 1/2] Fill old_value argument in timer{,fd}_xettime test

[Eugene Syromyatnikov]

It is needed in order to differentiate it from the value returned by the
call. As a consequence, it enables revealing possible bugs in syscall
parsers, for example, when the value read on syscall entering and not on
syscall exiting (as it is the case with timerfd_settime parser).

* tests/timer_xettime.c: Fill old.its field with value different from the
  expected one upon call return.
* tests/timerfd_xettime.c: Likewise.
