tests: Remove use of IDE disk for pseries floppy test

Adding an IDE controller for a machinetype that has no built-in IDE
controller, libvirt will log an error. Currently the machinetype list
which returns by qemuDomainMachineHasBuiltinIDE only includes 440fx,
malta, sun4u and g3beige.

Remove the disk and the .args file since the expectation is the test
will fail in qemuxml2argvtest because floppy is not supported on pseries
and thus no disk is necessary and no .args file would be created to
compare against.
