[bug#41756] [PATCH] gnome: gnome-desktop: Add bubblewrap as an input.

[Christopher Baines <mail@cbaines.net>]

This is expected to be available, oddly as libseccomp is available.  These
changes fix thumbnails for Nautilus.

* gnu/packages/gnome.scm (gnome-desktop)[arguments]: Add 'patch-bubblewrap
phase.
[inputs]: Add bubblewrap.
