autofs-5.0.7 - fix compilation of lookup_ldap.c without sasl

From: Dustin Polke <DuPol@gmx.de>

See https://bugs.gentoo.org/show_bug.cgi?id=361899 for more info.

Edited by: Ian Kent <raven@themaw.net>
- fix parse_ldap_config() is needed by ldap but previously excluded.
- exclude other references to ctxt->extern_cert and ctxt->extern_key.
- prevent memory leak if present in config but not used.
- remove now unused set_env().
