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

[ryan woodsmall]

Excellent point, Daniel. Try two is below. The verbuf string is tokenized on
newline, then iterated over with blank lines ignored. First match of the
VMware driver pattern will break out of the loop with tmp set correctly or
the default NULL if it's not found. This should allow vmwareExtractVersion
to work as expected without change and VMware Fusion/Player/Workstation to
continue working on OS X and Linux.

Tested successfully with VMware Player 5.0.3 and 6.0.1 on an SL6 box. Would
appreciate a Fusion test on OS X if possible.
