specfile: ship the *.OTF format files as well
Currently, LibreOffice is no longer able to use Type1/AFM formats
(which have their limitations).And we can expect the situation to
get even worse in the future, where other applications will start
dropping support for Type1/AFM as well.
Shipping same font in more than 1 format is forbidden by FPG, but
there's no way how to resolve this at the moment...
