oeqa/targetcontrol.py: modify it to test runqemu

Modify the following files to test runqemu:
    targetcontrol.py
    utils/commands.py
    utils/qemurunner.py

We need simulate how "runqemu" works in command line, so when test
"runqemu", the targetcontrol.py, utils/commands.py and
utils/qemurunner.py don't have to find the rootfs or set env vars.
