Backport two kscreenlocker patches from the 5.14 branch

- Force software rendering when greeter crashed:
- Load QtQuickSettings for software rendering (KDEBUG #347772):

In particular the second patch eliminates 100% CPU usage in the lockscreen
in case you have older hardware and rely on software rendering.
I think this warrants the backport into Slackware's Plasma5 Desktop.
