[PATCH 84/86] tests:numa-test: use explicit memdev to specify node RAM

[Igor Mammedov]

Follow up patches will remove automatic RAM distribution
between nodes and will make default machine types require
"memdev" option instead of legacy "mem" option.

Make tests to follow new rules and add an additional test
for legacy "mem" option on old machine type, to make sure
it won't regress in the future.
