dirmngr: Allow building without LDAP support.

* configure.ac: Add option --disable-ldap.
(USE_LDAP): New ac_define and am_conditional.
* dirmngr/Makefile.am: Take care of USE_LDAP.
* dirmngr/dirmngr.c (!USE_LDAP): Make all ldap options dummy options
and do not call any ldap function.
* dirmngr/server.c (!USE_LDAP): Do not call any ldap function.
* dirmngr/crlfetch.c (!USE_LDAP): Ditto.
