regression: unsuffixed cmdline arg treated as Lisp.

This broke in TXR 216. TXR files with no suffix run
using #!/path/to/txr stopped working due to being interpreted
as Lisp. The rearrangement done in open_txr_file function
didn't respect the hacky treatment of the *txr_lisp_p flag,
which depended on the original order. The flag ends up being
set to t, because we tried (unsuccessfully) opening a .tl
suffix, and that then falsely indicates "Lisp" when the
unsuffixed file is open. That logic worked when we tried the
unsuffixed file first, and fell back on the added suffixes
last.

* parser.c (open-txr_file): Instead of repeatedly testing
for in == 0, we execute a forward goto when we successfully
open a file. Only in those successful cases, set *txr_lisp_p
to the appropriate value, not touching it otherwise.
