[PATCH] Add googletest

[Lukas Gradl]

Hello Guix,

This patch adds googletest, a native-input for the c/c++ version of
msgpack (coming soon).

There is no "install" target.  At the moment the patch copies the build
results to out/lib and the include directory of the source tree to
out/include.  I am not sure if this is enough or if something else needs
to be installed.  Opinions are welcome!

Thank you!
