astribank_hook: startup lock and more

* Silently exit right away if user did not set XPP_HOTPLUG_DAHDI.
* Only one Astribank should be allowed to run the startup script:
  - Protect that section with a "lock" (symlinking a file).
  - Sadly we can't rely on /run and may have to wait for a r/w file-system.
  - And thus even this waiting needs to be run in the background
    as to not hold udev.
