XO_Packager: package files that are in git and the locale folder, OLPC #11217

There had been reports about Activities that had unexpected files in
the xo bundle (e.g. patches). There have been a recent change that the support
for the MANIFEST has been removed from the bundle builder. The MANIFEST
'controlled' which files were bundled. The code did include all the
files present in the folder (which includes patches etc).

The patch does use git-ls to get a list of files to include (like the
tarball packager). Furthermore the locale folder is included which has been
generated. Due to the API freeze we made '_get_files_in_git' a private method
which adds a bit of duplication to the 'get_files' method in the tarball
packager. A patch for master which will implement Builder.get_files_git(),
that can be used by XOPackager and SourcePackager.
