Remove unnecessary dom0 packages as default post-install step

I started looking into this to clean up my dom0. I'll edit this comment if I find more packages that can be removed. Here's the list so far:

• initial-setup-gui (note: removes Yelp but there wasn't really any content in Yelp anyway)
• openssh
• NetworkManager (note: removes some DHCP packages; not sure if these are involved in networking - also removes libblockdev, thus libblockdev-btrfs, thus btrfs-progs which may be a problem on btrfs roots)
• usbutils
• usb_modeswitch

I've only just rebooted, but so far everything seems OK with these packages gone.

More potential packages:

• xfsprogs, but that removes some other admin stuff that may be wanted like gdisk. Removes storaged and libsecret too but I'm pretty sure that's ok.
• zip
• xfce4-cellmodem-plugin
• xdg-user-dirs
• unbound-libs
• guile (removes openssl)

Note that the packages in the second list are just those I saw when looking. I haven't necessarily tested them and they may be in the second list because I don't fully understand the implications of removing them.

There are also some packages, e.g. glusterfs, that really don't belong, but removing them gives the error Error: The operation would result in removing the following protected packages: qubes-core-dom0. Seems like there's some (indirect) dependency weirdness going on.

I just discovered that there's initial-setup (and a whole bunch of its dependencies) installed as well, besides initial-setup-gui.
