Unretire unshield

[Ben Rosser]

Hi,

I'd like to unretire unshield.
https://src.fedoraproject.org/rpms/unshield/

This is a dependency of openmw (maintained by me in RPM Fusion).

The package was retired on 12/17, which was just under eight weeks
ago-- so I think a re-review is not necessary.

Releng ticket:

Thanks in advance,
