Accept pg_ctl timeout from the PGCTLTIMEOUT environment variable.

Browse Source 
Many automated test suites call pg_ctl.  Buildfarm members axolotl,
hornet, mandrill, shearwater, sungazer and tern have failed when server
shutdown took longer than the pg_ctl default 60s timeout.  This addition
permits slow hosts to easily raise the timeout without us editing a
--timeout argument into every test suite pg_ctl call.  Back-patch to 9.1
(all supported versions) for the sake of automated testing.
