To run user-mode emulation tests, we introduced the avocado_qemu.QemuUserTest which inherits from avocado_qemu.QemuBaseTest. System-mode emulation tests are based on the avocado_qemu.Test class, which also inherits avocado_qemu.QemuBaseTest. To avoid confusion, rename it as avocado_qemu.QemuSystemTest.
