deluge-1_x: Remove older version of Deluge (#134448)

Deluge 1.x requires Python 2 which upstream has end-of-lifed.  Deluge depends
on pythonPackages.twisted, Python 2 support for which upstream has
nowdropped.  If pythonPackages.twisted is upgraded then Deluge 1.x breaks.
So, remove it instead of leaving it broken.

Deluge 2.x (deluge-2_x) is available and continues to work.
