package/gtest: host-gtest install like a normal cmake package

Currently, host-gtest does not actually build and install gtest
libraries or header files; it just installs the gmock_gen stuff.

Host gtest can however be used by packages to build and run their
unit-tests natively.

This patch will now build and install gtest to the host like a normal
cmake package.

To limit the disruption for existing users of host-gtest, the gmock_gen
stuff is still installed (as a post-install hook now).
