Add gtest target support for runtest --path.

This is a rough initial version. It makes several assumptions:
 - assumes each test source file is built into module with name equal
to basename of source file
 - assumes tests get installed into /data/nativetest

However, given those assumptions, both:
$ runtest --path <path to directory containing gtest source> and
$ runtest --path <path to single source file>
should work.

Coming soon: gtest host support
