Allow user to specify git path for mirror repositories.

In some case, especially the local_manifest.xml file exists for mirror repos,
user may want to specify a different gitdir according to the 'path' attr.

For new mirror repos, append the '--force-path' option to the 'repo init --mirror' command.

For existing mirror repos, exec command 'git config --file=.repo/manifests.git/config repo.forcepath true'
