Fix RockboxInfo() not handling git hashes correctly.

With the transition to git the assumption of the version starting with "r"
isn't true anymore for non-release builds. This caused the wrong strings to be
used when constructing various download URLs.

Remove the test binary which was never intended to be added and fix some
warnings in the test implementation.
