FACT-694: ec2 facts doesnt work for kvm

The ec2 facter is restricted only for xen by matching
virtual fact to xen, because of this, ec2 facts doesn't
work for openstack with kvm hypervisor.

Fixed it by adding kvm also in the match.

(FACT-692) Fix issue with Solaris resolution of operatingsystemmajrelease

This commit corrects the naming of the method responsible for
determining the major release of SunOS systems, allowing Solaris 10
systems to correctly resolve the operatingsystemmajrelease fact.

With the addition of the structured operatingsystem fact, a new
class structure was created which includes a base class with
several platform specific children. The method within these
classes which is responsible for determining the operatingsystem
major release is named 'get_operatingsystemmajorrelease'. The
method was, however, misnamed in the SunOS class as
'get_operatingsystemmajrelease', which is never called, causing
the fact to fall back to the base class implementation.

This commit fixes this regression which was introduced in Facter 2.2.0
at commit 793b258.

(FACT-683) Use XPG4 variant of `id` in Solaris to determine GID

Prior to this commit, the GID fact would attempt to invoke the `/usr/bin/id`
variant of the `id` command in Solaris, which does not include the necessary flags to
determine the user GID in Solaris 10.

This commit updates the fact to instead use the more advanced `/usr/xpg4/bin/id`
for Solaris instead.
