Update packaging for Xfce 4.20

[marmarek]

This is meant for Fedora 42 (when used as GUI domain). Dom0 with older Xfce
should not get this package. This means this PR should not be actually merged
to main, but to a new branch, and .qubesbuilder in the main branch should be
adjusted to exclude distributions with Xfce 4.20.
