Add a unit test for testing the Android bootmethod.
This requires another mmc image (mmc7) to contain the following partitions: - misc: contains the Bootloader Control Block (BCB) - boot_a: contains a fake generic kernel image - vendor_boot_a: contains a fake vendor_boot image
Also add BOOTMETH_ANDROID as a dependency on sandbox so that we can test this with:
$ ./test/py/test.py --bd sandbox --build -k test_ut # to build the mmc7.img $ ./test/py/test.py --bd sandbox --build -k bootflow_android
