weston-init: Fix inoperable Weston desktop
For an image configured with pam and systemd, Weston apps
would fail to run. For example:
$ weston-terminal
failed to connect to Wayland display: No such file or directory
failed to create display: No such file or directory
This fix is based on a proposal by Daniel Diaz to OE-core. The
main part of the fix is the use of a new, manually created tty.
The original proposal called weston directly, but that didn't
seem to work where weston-launch did.
