[PATCH v2] gtk-icon-cache: Allow using gtk4

[Zoltan Boszormenyi]

From: Zoltán Böszörményi <zboszor@gmail.com>

meta-openembedded has gtk4 which has its own version of
gtk-update-icon-cache. Allow programs that want to use gtk4
use the proper version of the gtk-update-icon-cache utility
and the proper build and runtime dependencies.

Also use a more readable syntax for conditional values in DEPENDS.
