tests/acceptance: Makes linux_initrd and empty_cpu_model use QEMUMachine

On linux_initrd and empty_cpu_model tests the same effect of
calling QEMU through run() to inspect the terminated process is
achieved with a sequence of set_qmp_monitor() / launch() / wait()
commands on an QEMUMachine object. This patch changes those
tests to use QEMUMachine instead, so they follow the same pattern
to launch QEMU found on other acceptance tests.
