add powerpc_vsx_ok requirement to undef-bool tests

[Alexandre Oliva]

These tests use -mvsx in their dg-options list, so they are only
applicable if the -mvsx option is supported by the compiler.

Tested with target ppc64-vx7r2, configured to force altivec disabled,
and thus to reject vsx.  Ok to install?
