Fix flatpak build

File dependencies must only be used when the location is fixed.
However, perl is now built for flatpak consumption, meaning that
pod2man in the flatpak buildroot is in /app/bin, not /usr/bin.
Avoid any ambiguity by using the package name instead.

Also, polkit has changed to enabled to default, so it now needs to
be disabled for flatpak builds.
