Use Automake 1.11's parallel-tests feature.

* configure.ac: Enable parallel-tests.
* src/eltltest/defs.in, src/evtgbatest/defs.in,
src/ltltest/defs.in, src/tgbatest/defs.in: Always output verbose
tests.  Make a subdirectory for each test case.
* src/ltltest/Makefile.am, src/eltltest/Makefile.am,
src/tgbatest/Makefile.am, src/evtgbatest/Makefile.am: Remove
CLEANFILES and clean the test subdirectories in a distclean-local
rule instead.
