tests: Increase default VM memory from 128M to 192M

It looks like the 128M default memory size for the hwsim test setup was
not large enough to cover all the needs anymore. Some of the test cases
using tshark could hit OOM with that size. Increase the default
allocation to 192M to avoid this type of issues.
