[python-meh][trivialPATCH] Epoch of the package from RPM db can be None (#957789)

[Vratislav Podzimek]

None has to be replaced with some default ("0"), otherwise libreport raises
expcetion and bug reporting doesn't work.

libreport really ought to handle the possibility that it'll get a None
when it doesn't expect, but this is fine to do in python-meh too.  Can't
