pth: run make test

If pth is miscompiled, other software that uses it can fail
mysteriously without a clear indication of the source of the
problem. This causes problems with gnupg2 on some platforms,
for example.

pth's `make test` will reveal this kind of problem, so always run
that to be safe.

See: mistydemeo/tigerbrew#39.
