Use reference also for manifest git

When running 'repo init --reference=<mirror>', the mirror will be
used for all projects except the manifest project. This is because
the _InitGitDir function uses the 'repo.reference' git config
value specified in the manifest git, which has no effect when
creating the manifest git as that value will be set after the git
has been successfully cloned.

Information about where the manifest git is located on the server
is only known when performing the 'repo init', so that information
has to be provided when cloning the git in order for it to set up
a proper mapping.
