git-remote-mediawiki: add a git bin-wrapper for developement

The introduction of the Git::Mediawiki package makes it impossible to test,
without installation, git-remote-mediawiki and git-mw.

Using a git bin-wrapper enables us to define proper $GITPERLLIB to force the
use of the developement version of the Git::Mediawiki package, bypassing its
installed version if any.

An alternate solution was to 'install' all the files required at each build
but it pollutes the toplevel with untracked files.
