Max Reitz d81fe252a2 iotests: Do not pipe _make_test_img
Executing _make_test_img as part of a pipe will undo all variable
changes it has done.  As such, this could not work with FUSE (because
we want to remember all of our exports and their qemu instances).

Replace the pipe by a temporary file in 071 and 174 (the two tests that
can run on FUSE).
