Use gpgrt's new option parser for the remaining daemons.

* scd/scdaemon.c: Switch to the new option parser and enable a global
conf file.
* dirmngr/dirmngr.c: Ditto.
* g13/g13.c: Ditto.
* g13/g13-syshelp.c: Ditto.  Do not force verbose mode.
* dirmngr/dirmngr_ldap.c: Switch to the new option parser.
* dirmngr/dirmngr-client.c: Switch to the new option parser.
--

This finalizes the switch to the new option parser.  What's left is to
remove the old argparser code from common.

g13-syshelp does not anymore default to --verbose because that can now
be enabled in /etc/gnupg/g13-syshelp.conf.
