Fix desktop_to_dm in any::get_autologin() to handle new session names.

There are now multiple session files in /usr/share/xsessions and in
/usr/share/wayland-sessions for each DE, so the old hash table was
both broken and inadequate. Replace with a subroutine that uses
case-insensitive regex matching, which should be more future-proof.
