dir2module return wrong NEVRA if epoch is not 0

[unnilennium]

it seems that the work marked as todo could bite people encountering an epoch >0
with current code , it seems to alway go to 0 even if with rocky 8 /el8 we ecounter a package like mod_ssl that has epcoh to 1.

            # For some reason `nevra.release` contains also the architecture
            return "{N}-{E}:{V}-{RA}".format(N=nevra.name, E=nevra.epoch or 0,
                                             V=nevra.version, RA=nevra.release)

fix would be something like
