Florian Klink 6ac74d60ad networkmanager-pptp: remove package
Currently broken on NixOS due to hardcoded modprobe binary path (see
bug #30756 from Oct 2017), no activity on a proposed fix for months.
As the protocol is terribly broken anyways, let's better remove it
completely, and not talk about anymore ;-)

Closes #30756.
