VMWware: add option into VMTools config to enable/disable custom script.

VMWware customization already has support to run a custom script during
the VM customization. Adding this option allows a VM administrator to
disable the execution of customization scripts.  If set the script
will not execute and the customization status is set to
GUESTCUST_ERROR_SCRIPT_DISABLED.
