[libvirt] [PATCHv2] configure: disable network and storage-fs drivers on mac os x

[Justin Clift]

Disabling these two drivers on MacOS X, where they are known to
not work, allows libvirt (including the daemon) to compile without
any further changes.
---
This 2nd version of the patch incorporates Erics suggestion for a better case
statement approach, and fixes a typo in a comment.

Apart from that, this is the final patch needed to compile out of the box
on MacOS X.  (further work should be done at some point to fix the ssh
connectivity problem to PolicyKit enabled servers though)

Anyone with a BSD around, that wants to check there, in case we get lucky? :)
