 Child ticket of #15801.

 In `directory_permits_begindir_requests()`, a relay doesn't accept
 `BEGIN_DIR` cell if the DirPort isn't set.

 {{{
 int
 directory_permits_begindir_requests(const or_options_t *options)
 {
   return options->BridgeRelay != 0 || options->DirPort_set;
 }
 }}}

 Fixing this would make every relay being able to answer directory requests
 without a DirPort. Turns out, it's a part of proposal 237 so we should
 make those two happens and incidently helping with the global issue in the
 parent ticket.
