Attempt to only add/remove enman repos that need action

Since enman was changed to provide exit status 1 [1] if the requested
operation failed, builder attempting to re-add an already existing repo
caused the entire build to fail. Rather than run the command and hope
for the best, this commit changes builder to obtain a list of already
installed repositories, and only add/remove the requested repos that
aren't already in the correct state.
