Fix sync for symlink of component repos
Fix sync for symlink of component repos

The symlinks are not synched currently and
had caused outdated repos pushed to
trunk.rdoproject.org, which has caused the
issue [1] and then these wrong repos were pushed
ahead and caused [2].

This patch fixes the sync command to handle
the sync of symlinks.
