[PATCH] git.py: Remove -l option, its not necessary

[Richard Purdie <richard.purdie@linuxfoundation.org>]

If -l is specified and the source and destination are not on a common
filesystem an error occurs. The -l option is however the default for
git for local paths which the fetcher already now ensures in the
file:// case.

We can therefore safely drop the -l option.
