Detect virtualisation on netbsd (#18381)
* Refactor OpenBSD sysctl based detection in a separate class The idea is later to reuse this code for NetBSD and FreeBSD, who use a different sysctl key for vendor and product. * Add detection of virtualisation on NetBSD * Add support to detect running as a Xen guest tested on NetBSD 7 on Rackspace.
