(#6883) Update Facter install.rb to be slightly more informative.

Give slightly more information to the user when installing facter and the
pre-requisite Ruby libraries are not installed.

In the case of OpenSSL, the user can have OpenSSL installed, and not the
gem/library, but the error message given in no way hints to this.
