        Returns the persistent filename for the given data.

        `data` should be a date or datetime object if the build type is
        'nightly', else a changeset.

        if `regex` is True, instead of returning the persistent filename
        it is returned a string (regex pattern) that can match a filename.
        The pattern only allows the build name to be different, by using
        the fetch_config.build_regex() value. For example, it can return:

        '2015-01-11--mozilla-central--firefox.*linux-x86_64\\.tar.bz2$'
