autofs-5.1.0-beta1 - fix old style key lookup
From: Ian Kent <ikent@redhat.com>
Old (old) style configuration keys all started with DEFAULT_ but
the configuration entry lookup requires the has of the lower case
name. So trying to these old style names failes because thet don't
has to the same value.
So change the key lookup to strip the DEFAULT_ string and retry
the lookup so valid entries hash properly.
