[libstdc++] [testsuite] no libatomic for vxworks
libatomic hasn't been ported to vxworks. Most of the stdatomic.h and
<atomic> underlying requirements are provided by builtins and libgcc,
and the vxworks libc already provides remaining __atomic symbols, so
porting libatomic doesn't seem to make sense.
However, some of the target arch-only tests in
add_options_for_libatomic cover vxworks targets, so we end up
attempting to link libatomic in, even though it's not there.
Preempt those too-broad tests.
