build: fix broken build when we don't HAVE_ZLIB.

* parser.c (open_txr_file): Use liberal heaps of #if HAVE_ZLIB.
If there is no Zlib, and the caller explicitly requests a
.tlo.gz file to be loaded, then throw. Do not implicitly look
for a .tlo.gz file.

* stream.c (open_file): #if HAVE_ZLIB around a goto label that
is only used out of HAVE_ZLIB code, to eliminate unused label
warning.
