Fix printing of flags

Due to an error when adding the different current definition types, the
flags configuration field never said (none).  Now it does once again,
and there's no trailing space when printing flags.

     /* Print the flags */

-    if (cfg->flags == 0) {

     }
     if (cfg->flags & PDBS_CONFIG_FLAGS_GIVEBACK) {

+        chprintf(chp, " GiveBack");

     }
     chprintf(chp, "\r\n");
