opie-init: Handle qss startup properly and diagnostably.
* Based on Michael Krelin's patch in #2211, changed to restart qss
if exits, and log what happens. It turns out that after initial setup,
few OPIE service is essentially restarted (During "Please wait" white
screen), including qcop, on which qss depends, so qss quits. Plus, we
always should anticipate possibility of it segfaulting ;-).
* With this change, sound on pocketpc's works OOB, and as it worked
for zauruses with original patch, #2211 should be resolved.
