Since commit a2ce7dbd91 ("meson: convert tests/qtest to meson"),
libqtest.h is under libqos/ directory, while libqtest.c is still in
qtest/. Move back to its original location to avoid mixing with libqos/.

* 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.
