[Libguestfs] [v2v PATCH 1/2] test-v2v-fedora-btrfs-conversion: spell out btrfs feature group dependency

[Laszlo Ersek]

In case the libguestfs appliance lacks the btrfs feature group, we create
a zero-sized phony Fedora/BTRFS image variant, causing this test case to
fail. In that situation, the test should just be skipped.
