BaseTools: add repo name option to SetupGit.py

Allow users who didn't clone one of the TianoCore repos from a
canonical URL to specify the name of the repo (edk2, edk2-platforms
or edk2-non-osi) when running SetupGit.py to allow them to configure
their repo properly.

The new option is:

  -n repo, --name repo  set the repo name to configure for, if not
                        detected automatically
