test: pytest: support formats besides raw for --blk

So far, we hardcoded format=raw to avoid Qemu warnings about having to
guess file type. Instead move format=raw to the start, so other formats
can be appended as necessary. Example:

  pytest --lg-env test/arm/multi_v8_defconfig.yaml --interactive --blk=img.qcow2,format=qcow2
