dyndbg: reverse module walk in cat control 

JIRA: https://issues.redhat.com/browse/RHEL-28063

    dyndbg: reverse module walk in cat control

    /proc/dynamic_debug/control walks the prdbg catalog in "reverse",
    fix this by adding new ddebug_tables to tail of list.

    This puts init/main.c entries 1st, which looks more than coincidental.

    no functional changes.
