Add userdb packageconfig to control the building of the pam_userdb.so module.
This depends on dbm support being compiled in for the berkley db package.
Also, remove "--with-db-uniquename=_pam" from EXTRA_OECONF. It makes the checks
for libdb fail because it searches for the wrong symbols in libdb (and libdb
was not configured with --with-uniquename=_pam option).
db.do_configure:
checking if --with-uniquename=NAME option specified... no
libpam.do_configure:
checking for db_create_pam... no
checking for db_create... no
checking for dbm_store_pam... no
checking for dbm_store... no
checking for dbm_store in -lndbm... no
