main/postmarketos-ui-xfce4: clean up package section (MR 5805)

Use install "-t" option, avoiding to repeat the file name and allowing to add
more than one file per command. Additionally sort the commands alphabetically
per path.

Exception is the lightdm autologin config file because it does a file renaming.
Put this command to the end.
