[libvirt] [PATCH] vmware: make version parsing more robust

[Jean-Baptiste Rouault]

Since commit d69415d4, vmware version is parsed from both stdout and
stderr. This patch makes version parsing work even if there is garbage
(libvirt debug messages for example) in the command output.

Add test data for this case.
