testing/profanity: Remove dependencies on Xorg

Profanity can optionally support systray, notifications
as well as xscreensaver, but since it's a terminal-based
application, most (if not all) its users are likely
using it in a screen/tmux on a headless machine,
and don't need nor want those features.

This should close #12284
7 jobs for !16784 with profanity_nox in 2 minutes and 42 seconds (queued for 1 second)
