[Buildroot] [PATCH] Restore .git directory in git package downloads

[James Balean <james@balean.com.au>]

Removing the .git directory during package download and caching prevents
Builroot users from making and testing changes to external software
packages using Buildroot. This patch enables users to commit locally,
make patches and contribute back to the projects they are using.
