[PATCH 3/3] tests/qtest/pxe-test: skip per-row cases whose machine is unavailable

[Rohitashv Kumar <rohit.kuma1313@gmail.com>]

From: Rohitashv Kumar <roohiit@amazon.de>

The x86 test table mixes 'pc' and 'q35' rows. When QEMU is built without
the i440fx/pc machine, the 'pc' rows fail with "unsupported machine type".

Add a per-row qtest_has_machine() check in test_batch(), mirroring the
existing per-row qtest_has_device() guard, so rows for an unavailable
machine are skipped while the others (e.g. q35) still run.
