Increase pfctl timeout from 5 to 15 seconds.

Pfctl log contains "Pfctl no '(?^:updated addresses for pf table
.*: added: 1,)' in pfresolved.log after 5 seconds for 4 times at
Pfctl.pm line 48.".  Pfresolved log starts resolving
"parent_send_resolve_request: sending resolve request for foobar.regress.
(AAAA) to forwarder", but contains no answer.  Maybe the test is
not patient enough.
