tests/nbd: pass --format to qemu-nbd if possible

Browse Source 
Run `qemu-nbd --help` to know whether it supports --format, and if so
pass it explicitly.  This avoids warnings with newer qemu versions,
where they really recommends to explicit the format of disk images being
specified on command line.
