Reset ports maintained by horia@racoviceanu.com.

The last change submitted or approved by Horia in Bugzilla dates back to
September 2015. Since then, all commits to his ports were landed by others
after the maintainer timeout period expired (see r383744, r405055, r405057,
r400461 and r414655, for example).

Horia did show interest in coming back after I sent a private email a few
months ago, but since nothing has changed it is better to reassign his ports
back to the heap.
