nptl: Convert tst-sem5 & tst-sem13 to use libsupport

  From: Mike Crowe <mcrowe@brightsign.biz>

* nptl/tst-sem5.c: Remove unused headers. Add <support/check.h>. (do_test)
  Use libsupport test macros rather than hand-coded conditionals and error
  messages. Ensure that sem_init returns zero rather than not -1. Use
  <support/test-driver.c> rather than test-skeleton.c.

* nptl/tst-sem13.c: Add <support/check.h>. (do_test) Use libsupport test
  macros rather than hand-coded conditionals and error messages. Use
  <support/test-driver.c> rather than test-skeleton.c.

Adhemerval Zanella suggested[1] that I should migrate these tests to
use libsupport before adding the sem_clockwait function. This is my
attempt to do so.

LGTM, thanks.
