Fix fuzzy error handling in pg_basebackup when opening gzFile
First, this code did not bother checking for a failure when calling dup(). Then, per zlib, gzerror() returns NULL for a NULL input, which can happen if passing down to gzdopen() an invalid file descriptor or if there was an allocation failure. No back-patch is done as this would unlikely be a problem in the field. Per Coverity. Reported-by: Tom Lane
