Subject: (#9859) Add root_home fact and tests

Without this patch applied, the stdlib module does not provide a
root_home fact.  This fact is necessary to easily determine the root
account home directory on platforms Puppet is supported on.

The major variations this fact address are:
---
solaris: /
linux: /root
macosx: /var/root

Spec tests using rspec have been provided as well to cover these three
general cases.  Windows tests are marked as pending.
