machine e2e : set default disk size to 11

this default value for podman machine disk sizes is 100GB.  On CI
platforms where the IO is slow and some operations are not done
sparsely, this can really slow things down.

if no disk size is provided by the init command in the test suite, we
set it to 11G.
