Race in packer build using vmware-esxi.json

[Liam Young]

When running a packer build using vmware-esxi.json it continually fails for me. I believe the only place I have deviated from the instructions is that I am running the build on focal.

It seems that the /dev/nbd4 device is not ready immediately after the partprobe completes and so the subsequent mount command fails. I worked around this by editing the vmware-esxi.json and adding a 10s sleep after the partprobe and rerunning.
