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.
