[mythtv] Building fc25 master rpms fails after 30-Pre-23

[John Pilkington]

Not surprising.  I'm running 30-Pre-22 with fc25 and SL7 from a specfile 
based on one from rpmfusion.

> Disabling MythNetvision due to missing dependencies.

and then the packaging stage failed because of missing mythnetvision 
files.  I imagine that a build 'without mythnetvision' would have a 
similar problem later.

I'll just run with the current builds for a bit.
