Fix file descriptor leak after failure of a \setshell command in pgbench.
If the called command fails to return data, runShellCommand forgot topclose() the pipe before returning. This is fairly harmless in the currentcode, because pgbench would then abandon further processing of that clientthread; so no more than nclients descriptors could be leaked this way. Butit's not hard to imagine future improvements whereby that wouldn't be true.In any case, it's sloppy coding, so patch all branches. Found by Coverity.
