vm_tools: provide balloon_bias_mib arg to ARCVM

Pass `--balloon_bias_mib 48` argument to crosvm when starting ARCVM.
This value was determined by running the multivm.Lifecycle.arc_host and
multivm.LifecycleShifting.arc_host tests. Both tests consistently passed
with 32 and 64, but 48 provides a better balance between tabs_live and
apps_alive in multivm.Lifecycle.arc_host, meaning it is more fair.

Tests run on a hatch kled with 4/8G of memory.
