Avoid and detect SIGPIPE race in TAP tests.
Don't write to stdin of a psql process that could have already exited with an authentication failure. Buildfarm members crake and mandrill have failed once by doing so. Ignore SIGPIPE in all TAP tests. Back-patch to v10, where these tests were introduced. Reviewed by Michael Paquier. Discussion: https://postgr.es/m/20171209210203.GC3362632@rfd.leadboat.com
