[libvirt] [vmware] Fix VMware driver version checking on Linux

[ryan woodsmall]

Below works, but it still special cases Fusion. I'm not sure it's better, but
I think the VMWARE_DRIVER_FUSION pattern string could be changed to just
"VMware Fusion " then tmp checked against "Information:" and discarded
if a match is found using the tokenized output of virStringSplit. Something
like this in the loop over the tokenized driver command check output:

**
if ((tmp == NULL) || (strncmp(tmp, "Information:", strlen("Information:")) == 0))
    continue;
**

This could potentially be extensible with an array of discard substrings for
each VMware driver that are iteratable. That may be a bit outside my grasp...

Am I completely barking up the wrong tree here? Heading to bed, sorry for the
bad patches!
