xserver-nodm-init: Fix X start failure on some platform

sudo is used to run rootless X in xserver-nodm, and start to fail with
"xf86OpenConsole: Cannot open /dev/tty0" error after upgrade to 1.8.1. sudo
seems wait for some resource that is unavailable in early phase of booting.
This patch swith to "su" for rootless X starting as a fix.

[YOCTO #1211] got fixed
