[LTP] [PATCH V4 1/5] syscalls/clock_gettime: Add support for time64 tests

[Cyril Hrubis]

Hi!
Pushed with a few changes, thanks.

* Changed the nonzero check to check if nanoseconds are valid,
  which covers the 64bit check as well.

* Pushed the bad address handling down to the test, which means that
  we have to convert the struct tst_ts for each syscall, but I think
  that it's cleaner that way and we also map only single bad address per
  test.
