[PATCH 04/10] tests/avocado: machine aarch64: standardize location and RO/RW access

[Cleber Rosa]

The tests under machine_aarch64_virt.py do not need read-write access
to the ISOs.  The ones under machine_aarch64_sbsaref.py, on the other
hand, will need read-write access, so let's give each test an unique
file.

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