Turns out the @^ construction for pulling in comps environment groups
doesn't work in kickstart, for reasons unknown.
This reverts commit 6c3c08f4425662b36a4ea4b3b89d3223a9a43ef5.
Add fedora-release-nonproduct to fedora-live-base.ks to ensure it gets
pulled in for all spins. In order to avoid it getting pulled in to
the Workstation product that is also based on fedora-live-base.ks,
explicitly exclude fedora-release-nonproduct in workstation kickstart
file.

Drop most package removals / additions from the kickstart file and rely
on the @workstation-product comps group pulling in the correct packages.
We'll need package selection done in comps in order to make Workstation
netinstall work properly.

icedtea-web clutters the application view with two launchers for config
dialogs which are not really apps as we define the term.
It used to be excluded previously but accidentally slipped back in with
the live-desktop -> live-workstation kickstart renames; this commit
takes it out again.
