This commit backports revisions 00938b2b228f3b70d3d9e51f29a1505bdad43f1e and
59f90a338bce2376b540ee239cf4e269bf6d68ad from googletest's master branch to
our included version of googletest, which is based on 1.8.1. It adds the
GTEST_SKIP feature, which is very useful for a project like FreeBSD where
some tests depend on particular system configurations.

The key difference is that some of the programs were previously being compiled
and installed as tests, which is incorrect. Treat them like helpers instead.
The former is from googletest.test.mk, whereas the latter is from plain.test.mk.
As noted in r344328, Kyua will adopt more native GoogleTest support. Thus, it's
more desirable to make the test interface more of an opaque blackbox for the
testcase implementer.
