user/livecd-support: Many improvements

* Change install scripts to local.d scripts.

* Add a local.d script to make dhcpcd setuid. (adelie/horizon#361)

* Make the Desktop Entry file a real file instead of a heredoc.

* Remove setuid bit from the shell script; we don't need this any more.

* Pull in our new LXQt theme for a better experience.

* Add XFCE subpackage.

* Set PATH correctly for horizon-run-qt5 so it can find mkfs.vfat and
  friends.

* Set the clock with chronyd if possible on boot, before the graphical
  environment starts.

* Use sudo for partitionmanger. (adelie/horizon#368)
