Bin Meng 94add6ee24 tests/qtest: prom-env-test: Use double quotes to pass the prom-env option
Single quotes like -prom-env 'nvramrc=cafec0de 4000 l!' in the arguments
are not removed in the Windows environment before it is passed to the
QEMU executable. Such argument causes a failure in the QEMU prom-env
option parser codes.

Change to use double quotes which works fine on all platforms.

* This test is used to check that some Open Firmware based machines (i.e.
* OpenBIOS or SLOF) can be started successfully in TCG mode. To do this, we
* first put some Forth code into the "boot-command" Open Firmware environment
* variable. This Forth code writes a well-known magic value to a known location
* in memory. Then we start the guest so that the firmware can boot and finally
* run the Forth code.
* The testing code here then can finally check whether the value has been
* successfully written into the guest memory.
