Title: skip adding floppy again in vmx_data_post step

With the new `vmx_data_post` of #1149 / #1152 I have the problem that the floppy is not unmounted properly.
Watching the progress with PACKER_LOG showed me more details:

First the floppy is unmounted, but afterwards added again to the vmx file.

My PR skips this floppy mount in the StepConfigureVMX for the VMXDataPost config.
The final vmx file has no floppy mounted, but the additional vmx_data_post config entries.
