iotests: Prepare for refcount_bits option
Some tests do not work well with certain refcount widths (i.e. you
cannot create internal snapshots with refcount_bits=1), so make those
widths unsupported.
Furthermore, add another filter to _filter_img_create in common.filter
which filters out the refcount_bits value.
This is necessary for test 079, which does actually work with any
refcount width, but invoking qemu-img directly leads to the
refcount_bits value being visible in the output; use _make_test_img
instead which will filter it out.
