beaglebone: start qtlauncher only after /dev/fb0 exists

Beaglebone creates /dev/fb0 late in the boot process, which causes
Qt applications to crash if started too early. Make systemd notice
fb0 creation and bind application startup to it.

(cherry picked from commit 300a9420bce2bcf4e0fffe30dae5cb0504e2cadb)
