tests/functional/test_acpi_bits: Turn the test into a QemuSystemTest

By using QemuSystemTest as a base class, we can use the set_machine()
command to check whether the required machine is available in the
binary (otherwise this test is failing when QEMU has been compiled
without the default 'pc' machine type).
