[OE-core] weston-init: run login before start weston.service

[quanyang.wang at windriver.com]

From: Wang Quanyang <quanyang.wang at windriver.com>

When systemd start the weston.service, the script "weston-start" will
check if the dir "XDG_RUNTIME_DIR" (usually is /run/user/0) exits and
create it. Then weston will create a socket file "wayland-0" for communications
with clients in this dir.

If systemd is built with enabling "pam" feature, the login will call "run-user-0.mount"
to mount tmpfs at the dir "/run/user/0", then the socket file "wayland-0" will be
missing since it is created in the old "/run/user/0".

So add "PAMName=login" to let weston.service call login first, once tmpfs is mounted at
"/run/user/0", then call weston-start to create a socket file in it.
