td-dvb-wrapper: add dependency on td-drivers
adapt initscripts to TD environment

populate-volatile.sh:
* old kernel and new busybox ash have problems reading from
  /proc/cmdline, skip this
* TD has no VT, so output errors to /dev/console
banner.sh:
* do not probe nonexistant VTs
* create compat symlink from /dev/tts/1 to ttyS1 for login getty
update machine config

* TD has no VTs
* Console is on ttyS1, not ttyS0 (tts/1 in reality)
* Kernel is too old for udev
