[PATCH v2 4/9] tests/avocado: machine aarch64: standardize location and RO access

[Cleber Rosa <crosa@redhat.com>]

The tests under machine_aarch64_virt.py and machine_aarch64_sbsaref.py
should not be writing to the ISO files.  By adding "media=cdrom" the
"ro" is autmatically set.

While at it, let's use a single code style and hash for the ISO url.
