[OE-core] [meta-oe][PATCH v3 2/4] testimage: consider QB_DEFAULT_FSTYPE

[Adrian Freihofer]

testimage.bbclass starts qemu with the first image type found in
the IMAGE_FSTYPES list. It's weird: this ['wic', 'tar'] works but
this ['tar'. 'wic'] does not. If QB_DEFAULT_FSTYPE is defined,
this fstype is booted.
