Issues with `--gog` when using unrar-free as a backend

[plaes]

Fedora, by default provides unrar-free package when installing unrar, which doesn't seem to support various features utilized by innosetup (?) like password protected (encrypted) archives (S.T.A.L.K.E.R. - Shadow of Chernobyl installer) and multi-file archives (S.T.A.L.K.E.R. - Call of Pripyat installer).

It is possible to install unrar via rpmfusion-nonfree repository which makes things work.

~Another possibility could be switching to p7zip instead...~
