[PATCH] pthread tests: fix missing-declarations warning.

[Bernhard Voelker]

Running tests on GCC-9.1.1 with -Werror stops at:
  test-pthread-cond.c:87:1: error: no previous declaration for \
    'test_pthread_cond_wait' [-Werror=missing-declarations]
     87 | test_pthread_cond_wait ()
        | ^~~~~~~~~~~~~~~~~~~~~~

* tests/test-pthread-cond.c (test_pthread_cond_wait): Declare static.
