[Buildroot] [PATCH 4/4] support/testing/tests/fs/test_ext: add missing "format" option for Qemu

[Thomas Petazzoni]

Will avoid the following warning:

   WARNING: Image format was not specified for
   '/home/thomas/projets/outputs/TestExt3/images/rootfs.ext3' 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.
