testsuite: Require thread-fence for 29_atomics/atomic_flag/cons/value_init.cc
A recent patch made __atomic_test_and_set no longer fall
back to emitting non-atomic code, but instead will then emit
a call to __atomic_test_and_set, thereby exposing the need
to gate also this test on support for atomics, similar to
r14-3980-g62b29347c38394.
libstdc++-v3:
* testsuite/29_atomics/atomic_flag/cons/value_init.cc: Add
dg-require-thread-fence.
