qtest: Don't compile qtest accel on non-POSIX systems

qemu with hax to log dma reads & writes jcs.org/2018/11/12/vfio

qtest_available() will always return 0 on non-POSIX systems.
It's simpler to just not compile the accelerator code on those
systems instead of relying on the AccelClass::available function.
