dirmngr: Fix lost flags during LDAP upload

* dirmngr/ldapserver.c (ldapserver_parse_one): Turn LINE into a const.
Use strtokenize instead of strtok style parsing.
--

This fixes a problem with resulted in a General Error for the second
key to be uploaded in the same session.  But only if the colon format
to specify a keyserver with flags was used.
