Don't reuse CID while Android is up
As virtualizationservice has become a lazy AIDL service, it started to
reuse CID, because a new virtualizationservice process always starts
from the default CID 10.
This has caused some flakness to tests because the adb connection to the
VM for a test sometimes goes to another VM that was started for a prior
test - because they both have the same CID 10.
Fixing this issue by introducing a system property
`virtualizationservice.state.last.cid` to keep the last CID value across
the runs of virtualizationservice. Note that the system property is not
persistent; a reboot of the host Android starts from CID 10.
