test: boot: Add test for bootmeth_rauc

Add a simple unit test for testing the RAUC bootmethod. Provide only the
very basic tests for now, running a scan and list, to verify correct
detection of the RAUC bootmethod. More advanced boot tests of this
bootmethod can be added in a separate patch.

This requires another mmc image (mmc10) to contain the following
partitions:

1. boot A: contains a dummy boot.scr
2. root A: contains an empty root filesystem
3. boot B: contains a dummy boot.scr
4. root B: contains an empty root filesystem

The bootmeth_rauc scans all four partitions for existence and expects a
boot script in each boot partition.

Also add BOOTMETH_RAUC as a dependency on sandbox so that we can test
this with:

$ ./test/py/test.py -B sandbox --build -k test_ut # build the mmc10.img
$ ./test/py/test.py -B sandbox --build -k bootflow_rauc
