Makefile: further improvement of tests.

The problem is that if a test is interrupted, it will not be
re-run because the .ok stamp file depends only on an .out
file, and that has been successfully created.

We completely remove .out files from the rule tree. Quite
simply, the output of a test is the .ok stamp. If that is
out of date or doesn't exist, the test is run. Generation
of the .out is just a side effect.

* Makefile (TESTS_OK): Calculate this variable directly from
the wildcard over .txr and .tl files..directly rather than
from TESTS_OUT.
(TESTS_OUT): Variable removed.
(TXR_OPTS, TXR_ARGS):  The target-specific assignments of
these variables for specific tests is now done against .ok
stamp file targets rather than .out targets.
(TST_EXPECTED, TST_OUT): New helper variables for condensing
repeated instances of some syntax.
(tst/%.out): Both of these rules are turned into rules
which target tst/%.ok. The .out files are just a side effect;
the goal is to update the stamp. If an .out file is removed,
the test won't be re-run; only if an .ok file is removed,
or any of the real prerequisites change.
(%.ok): This rule disappears, and its body containing the
conditional stamp file touch is moved into both tst/%.ok
rules.
