description:
Print db> prompt in db_read_line(), not db_readline().

The former is what DDB repl calls.  The latter performs the actual
input so let other code use it without the unwanted db> prompt.  It's
already used by ACPI (and AcpiOsWaitCommandReady supplies its own
prompt).  I also use it for my uncommitted Forth scripting for DDB.
