tests: Specfiy Qemu with a single environment variable

This allows Qemu to work out of the box if the user has an appropriate
Qemu installed.

Support for running TCG power guests has come a long way from when we
first added these test scripts. It makes sense to use the system Qemu
where possible, as for most people this will succeed.
