unit-test: Output googletest binaries with debugging info

A previous change b1da12722a7a8e8cb95be004e0f0aa4b22094001, added
debug symbols for dev versions of installed packages inside the unit test
container. Since googletest is also a development dependency and is
often involved in the debugging process, make sure it produces the
debugging symbols inside of its binaries.
