weston-init: Add possibility to run weston as non-root user

These changes are from meta-96boards primarily
Launch the session via a udev rule based on what kind of display device
is available

delete weston-conf and move the fuctionality into weston-init other
layers are doing same

weston-init installs machine specific weston.ini therefore mark is
machine specific now
