Subject: [PATCH 1/3] selftests: timers: Fix posix_timers ksft_print_msg warning

After commit 6d029c25b71f ("selftests/timers/posix_timers:
Reimplement check_timer_distribution()") I started seeing the
following warning building with an older gcc:

posix_timers.c:250:2: warning: format not a string literal and no format arguments [-Wformat-security]
  250 |  ksft_print_msg(errmsg);
      |  ^~~~~~~~~~~~~~

Fix this up by changing it to ksft_print_msg("%s", errmsg)
