Fix SIGPIPE flake in 01_engine-xfread under pipefail

The test matched engine output with `echo "$out" | grep -q PATTERN`. Under
`set -o pipefail`, grep -q exits the moment it matches, so echo takes a SIGPIPE
writing the rest and the pipeline reports failure even though the pattern was
found. The `|| { echo FAIL; exit 1; }` guard then fired on a passing case,
turning it into an intermittent, output-size-dependent failure (seen on the
Debian buildd leg of #632).

Match with here-strings instead, dropping the pipe and the race entirely.
