[bug#56299] [PATCH] gnu: Added breeze-gtk package.

[Samuel Fadel]

I personally like my GTK and Qt programs to have a consistent look. I
noticed the GTK port of the Breeze theme was missing from the repos, so
this is adding it.

I am unsure about the licensing as their current repo mentions both the
LGPL 2.1 and BSD 3-clause. How should I set it properly? Is just LGPL
2.1 enough?
