tests: specify format=raw for qemu to avoid warning

WARNING: Image format was not specified for
         '/var/tmp/systemd-test.tGi3od/rootdisk.img' and probing guessed raw.
         Automatically detecting the format is dangerous for raw images, write
         operations on block 0 will be restricted.  Specify the 'raw' format
         explicitly to remove the restrictions.

Also use unsafe caching mode, we don't care about data integrity here.
