Subject: gnu: gnome-shell: Avoid top-level reference to inkscape.

Fixes <https://bugs.gnu.org/34806>.
Reported by Marius Bakke <mbakke@fastmail.com>.

* gnu/packages/gnome.scm (gnome-shell)[source](snippet): Remove
reference to INKSCAPE.  Instead, simply copy the SVG file to
data/theme.
[arguments]: Add 'convert-logo-to-png' phase.
[native-inputs]: Add INKSCAPE.
