Subject: [PATCH] Tests: Simplify CTest.UpdateGIT repo path construction

Avoid constructing full paths to .git repositories in the test.  Use
relative paths and let Git convert them to absolute paths internally.
This is simpler and also avoids trouble with various absolute path root
component conventions on Windows (`c:/`, `/c/`, `/cygdrive/c/`).
