Puppet apply does not add the stdlib lib directory to the $LOAD_PATH.

puppet_settings library to be available for the
with_puppet
utilitymethod.
Without this patch, puppet apply will result in the following error:
With this patch applied, puppet apply works as expected:
This patch defensively tries to load facter/util/puppet_settings. If it cannot
load it, it falls back to trying to explicitly locate and load the library.
Once puppet is fixed such that a modules lib directory is truly in the
$LOAD_PATH, the fall back implementation will no longer be exercised since the
LoadError should not be raised.
