[PULL 17/23] tests/qtest: Add s390x virtio net PCI test to pxe-test.c

[Eric Farman <farman@linux.ibm.com>]

From: Zhuoying Cai <zycai@linux.ibm.com>

Add test coverage for virtio-net-pci network booting on s390x by
including it in the PXE test suite. The test verifies that PXE
network booting works correctly with virtio-net-pci devices.
