 `circuit_expire_building` can only close a circuit with this purpose with
 reason == `END_CIRC_REASON_TIMEOUT`.  Which seemed odd...

 > The assertion occurred in the following chunk of code, added to help fix
 #3825:
 {{{
  } else if (circ->purpose == CIRCUIT_PURPOSE_C_INTRODUCING &&
              reason != END_STREAM_REASON_TIMEOUT) {
 }}}

 ... but `END_CIRC_REASON_TIMEOUT` is not equal to
 `END_STREAM_REASON_TIMEOUT`. Oooops.
