(PUP-2478) Remove current directory from Ruby load path.

The current directory ('.') is on the load path for Ruby 1.8.7.
This is a security vulnerability as it allows arbitrary code loading if
users create ruby source files with names that correspond to those that
puppet is trying to load.

The fix is to explicitly remove '.' from the load path before any code
is loaded by puppet.
(PUP-2533) Apache 2.4 requires explicit CRL configuration

In Apache 2.2, if either the SSLCARevocationFile or SSLCARevocationPath
directives were specified then the specified file(s) would be checked
when establishing an SSL connection. Apache 2.4+ the
SSLCARevocationCheck directive was added to control how CRLs were
checked when verifying a connection and had a default value of none.
This means that Apache defaults to ignoring CRLs even if paths are
specified to CRL files.

This commit updates the debian postinst script for the
puppetmaster-passenger package to set SSLCARevocationCheck directive to
'chain' when Apache 2.4 is installed. This ensures that the the
puppetmaster-passenger vhost respects CRL files in the same way that
Apache 2.2 does by default.

(PUP-2683) Fix fact terminus to load facts without '.' on the load path.

The fix to PUP-2478 removed '.' from the load path, which only affected
Ruby 1.8.7.  However, the fact terminus does "load <filename>" to load
module facts.  In Ruby 1.8.7, this will fail to load because '.' is no
longer on the load path.  In Ruby 1.9.3+, loading with just a filename
assumes the current directory even without '.' on the load path.

This commit fixes the issue by joining '.' with the filename which
works in all currently supported Ruby versions.
