Splitt of the actual rescue root filesystem to
image-rauc-rescue-initramfs and build image-rauc-ubi using
kernel+initramfs (like normal rauc slots).

* We never need the BTS firmware. We never want to do GSM from
within rescue image
* Remove various udev hardware dbs. I think we couldn't care less
about identifying peripheral devices by name and such.
The system should be as small as possible and besides tools to
touch flash and block files, SSHD and rauc there should be nothing
else. We might continue to have opkg on it to allow updating it
The partition layout needed for rauc is different from the one created
by the existing installer (based on the live image).
An initramfs-framework module for installation to the sysmocom-idu is
added. It is included in a corresponding initramfs image for use on an
USB memory stick.
