Print deprecation notice when running SUID

Browse source 
Tracking swaywm/sway@e1db1f8

Add soft deprecation warning to highlight future intent of removing the
code which drops SUID privileges. libseat now has a better alternative in
the form of seatd-launch which uses the normal seatd daemon & libseat
backend and takes care of SUID.

Fixes issue #212
