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.
