sysmobts-config: Add script with postinst hook

Add post install script that will mangle the config to be the
right one for the given machine. This will be executed once
after the post installation. In case of the getty change the
system must re-start once to be fully usable. E.g. for the
sysmoBTS2050 the PA might not be powered up on first boot.
