oeqa/targetcontrol.py: fix qemuparams not work in runqemu with launch_cmd
As runqemu with launch_cmd means directly run the command, don't need set
rootfs or env vars.
Since commit [
a847dd7202 runqemu: Let qemuparams override default settings]
applied in oe-core, if launch_cmd contains "qemuparams='***'", it does not
work, which is overridden by latter qemuparams="-serial tcp:127.0.0.1" in
QemuRunner.launch();
So we set qemuparams as a parameter in runqemu, the fix makes it work
