(maint) Update debian/rules to use new --ruby flag

This updates the install.rb call in debian/rules to use the new --ruby flag and
sets the ruby binary location to /usr/bin/ruby, as is the standard on
debian/ubuntu installations. This is preferred to using env ruby as is in the
facter binary because that depends on the users' path, and might not bring in
the expected ruby.

Update default cows

Previously, the default cows were set to build for both arches.  Because facter
is a noarch debian package, building against i386 cows is sufficient and
reduces overall build time. This also adds cows for debian stable and unstable.

Update default cows
Remove asc file a source for RPM builds

We used to require the asc file for RPM builds of facter.  This was not
consistant with our packaging of any other platform and raised the
barrier to entry if you were trying to build your own facter package.

This commit removes the requirements of signing the tarball for building
an RPM package.  Tarball will still be signed prior to official release
from Rel-Eng team at Puppet Labs.
Spec file cleanup

This commit removes the Config, RbConfig switch which was needed for ruby 1.8.1
compatibility, as 1.8.5 is the minimum supported ruby. It also updates the
license to a valid correctly named license. It removes comments from some
%global macros as well. It also adds the epoch to the changelog entry.
Remove INSTALL from Facter

The INSTALL file dates back before there were packages besides gems for Facter.
As there are now packages for most major platforms, the INSTALL file isn't
needed. This removes it from the tree and from packaging.
Remove CHANGELOG from Facter

This commit removes the CHANGELOG file in the top level
of facter, which only contains commit hashes/ messages
from the previous releases, and is of debatable utility.
This information can be gleaned easily from a git log,
and is not of much use without git. Removing it removes
yet another manual process from the releasing of facter.

It also removes references of the CHANGELOG from the packaging.

Only load rubygems in bin/facter

We should not load rubygems when used as a library. Instead we require
rubygems when invoked from the command line.
(#16829) Change how bundler is detected

The constant `::Bundler::Setup` isn't defined in the latest version,
instead using just `::Bundler` to detect whether it's been loaded.

(#14764) Stop calling enum_cpuinfo and enum_lsdev on unsuitable platforms

Without this patch, the platform specific utility methods on
Facter::Util::Processor named enum_cpuinfo and enum_lsdev are always
called when Facter loads processor.rb.

This is a problem because exceptions will be raised during spec tests on
different platforms as described at
https://projects.puppetlabs.com/issues/14764
