(maint) Replace shell logic for OS release with Facter

To generate the correct init script components, install.rake
was shelling out to get a static field from /etc/redhat-release.
This is a fragile technique and Facter uses a much more robust
technique to derive the correct value across numerous RPM-based
platforms. This technique was part of the 1.7.x Facter branch,
so a build-time dependency has been added on Facter 1.7.0 or greater.

(maint) Replace shell logic for OS release with Facter
(maint) Explicitly set LANG in RPM spec file

LANG is set to 'C' by default, which is problematic because numerous
parts of Ruby have to parse UTF8 files. This will solve a problem with
Fedora 19, which has an umlaut in the release name. If LANG is
set to 'C', the umlaut then leads to unexpected values returned from Facter.
