VMX property values that can contain '=' characters break parsing due to how loadVMXMap() is implemented:

This came up while trying to create machines with https://github.com/hooklift/terraform-provider-vix using this https://app.vagrantup.com/generic/boxes/ubuntu1804/versions/3.0.10/providers/vmware_desktop.box Vagrant box.

The box has a guestos.detailed.data property defined with the value bitness='64' distroName='Ubuntu' distroVersion='18.04' familyName='Linux' kernelVersion='4.15.0-76-generic' prettyName='Ubuntu 18.04.4 LTS'

I'll submit a pull request.
