[PATCH 2/3] tests/qtest/drive_del-test: skip pc tests when 'pc' machine is unavailable

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

From: Rohitashv Kumar <roohiit@amazon.de>

test_cli_device_del(), test_device_add_and_del(),
test_drive_add_device_add_and_del() and
test_blockdev_add_device_add_and_del() use "-machine pc" on i386/x86_64.
When QEMU is built without the i440fx/pc machine, these fail with
"unsupported machine type 'pc'".

Skip the x86 case when 'pc' is not available. Non-x86 architectures use
the default machine and are unaffected, and the corresponding _q35
variants already cover x86 under qtest_has_machine("q35").
