MPTCP requires longer timeouts in pollin test due to subflow establishment
delays and slower state transitions. Increase timeout values to prevent
false failures:

 #  RUN           tls.13_sm4_ccm_mptcp.pollin ...
 # tls.c:1411:pollin:Expected poll(&fd, 1, 20) (0) == 1 (1)
 # tls.c:1412:pollin:Expected fd.revents & POLLIN (0) == 1 (1)
 # pollin: Test failed
 #          FAIL  tls.13_sm4_ccm_mptcp.pollin
 not ok 357 tls.13_sm4_ccm_mptcp.pollin
