Moving kpmcore to pkg-qt-kde/kde-extras

["Jonathan Carter (highvoltage)" <jcarter@linux.com>]

Hi Rohan

I meant to create kpmcore in pkg-qt-kde/kde-extras/kpmcore and found
that there's the older copy of yours in there.

Can I force push over that or do you care about the brief history it had
from 2015? It doesn't seem so important since that version was never in
the archives.

thanks!
