(CFACT-70) Fix Kernel and OS facts for solaris and add id and timezone posix facts

This patch adds the posix timezone and id facts (unchanged) to solaris
These are the only posix facts left that can be added directly to solaris
without change in behavior.

This patch also corrects the operating system facts and kernel facts so that they are inline with
the ruby facter output on the same platform.
If we're expecting only one value to be set, we should return false once we set it to break out of the loop.
