SL 7.7 update

[John Pilkington]

I have 7.7 running.  Part of the update went ahead with --skip-broken, 
but qt5-webkit (epel) and libreport-rhel-anaconda-bugzilla still caused 
problems.

qt5-webkit from epel-testing pulled in others of the family, and I don't 
see the libreport-rhel-anaconda-bugzilla package in the repos I use, so 
I erased it.

HTH,

John P
