opie-taskbar: Comment out getkey calls, as no longer available with current OE's busyboxes.
* Closes #1649.
* Few TODOs for this package:
1. Drop htcuniversal/opie - it only sets TS/keys devices, and that should be done
by other means (and need for that is questionable, as other HH.org devices work
without any explicit sets).
2. Move OPIE startup scripts to own package out of app package.
