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.
