postgresql: drop bashisms from ptest runner

run-ptest has a #!/bin/sh shebang but used two constructs that are not
available in the target /bin/sh (dash), so the suite died immediately
after starting the server and reported no test results at all:

  run-ptest: line 54: stdbuf: not found
  run-ptest: line 58: syntax error: bad substitution
  ERROR: Exit status is 2

${PIPESTATUS[0]} is a bash array reference; dash has no PIPESTATUS and
fails with "bad substitution". stdbuf is coreutils-only and is not
guaranteed to be installed on the target.

Capture pg_regress output to a temporary file and use $? directly
instead of piping live into sed, which removes the need for both
PIPESTATUS and stdbuf while keeping the same PASS:/FAIL: translation.
