[yocto] [meta-raspberrypi] Zenity is in meta-gnome

[Paul Barker]

rpi-first-run-wizard depends on zenity, which is in meta-gnome.
However the README file for meta-raspberrypi says only oe-core and
meta-oe layers are required (lines 105 and 106 of the current README).

I'd say the 2 possible solutions are either listing meta-gnome as a
layer dependency or re-writing rpi-first-run-wizard to use something
else. I can write a patch for the former, the latter isn't really my
area of expertise.

Thoughts?
