Fix compilation of pop3d and maidag without DBM.

* maidag/Makefile.am: Load libmu_dbm.la if MU_COND_DBM is true.
* pop3d/apop.c (pop3d_apopuser): Set owner, if specified in the
config.
* pop3d/pop3d.c (apop_database_owner)
(apop_database_owner_set): New globals.
(pop3d_cfg_param) <apop-database-owner>: New keyword.
* pop3d/pop3d.h (apop_database_owner)
(apop_database_owner_set): New declarations.
