gpgconf: Tweak the use of ldapserver.
* tools/gpgconf-comp.c (known_options_gpgsm): Make "keyserver" invisible. (known_options_dirmngr): Add "ldapserver". * sm/gpgsm.c (oKeyServer_deprecated): New. (opts): Assign "ldapserver" to the new option and makr it as obsolete.
We want to use "ldapserver" in dirmngr but need to keep using
"keyserver" in gpgsm for existant versions of Kleopatra etc.
