needles: disk selection GTK+ 3.20 workaround, part select update

Some needle changes to account for latest Rawhide. There seems
to be a bug between anaconda and GTK+ 3.20 causing text in the
disk selection widget not to be styled correctly: this commit
adds needles for that which are tagged as 'workaround', meaning
openQA will complete the tests but mark them as requiring a
workaround to work ('soft fail'). The bug is #1322036. There is
also an intentional change to the volume list in custom part;
the mount point names are now in dark grey rather than black (in
fact this has always been intended, but it's been broken for a
long time, according to davidshea). I cleaned up the part select
needles at the same time; the new ones have the non-variant
names, as davidshea says the same change is coming to F24 and
the original needles haven't matched for months. The F23 Atomic
install test doesn't hit any of these needles, so we don't need
to keep the original needles around for that. The most recent
variants are kept, as they'll be needed for F24 tests until the
new anaconda build goes stable for F24. The 'freetype262'
variant of part_select_swap hasn't matched for two months and is
dropped.
