test-canonicalize-lgpl: consolidate into single C program
Testing canonicalize bugs is easier if the setup can be run under
control of the debugger, rather than in a driver script. As a
bonus side effect, parallel testing with test-canonicalize no
longer competes for the file name "./ise".
* tests/test-canonicalize-lgpl.sh: Delete; move setup into...
* tests/test-canonicalize-lgpl.c (main): ...the program, making it
easier to run in debugger. Add some tests.
* modules/canonicalize-lgpl-tests (Files): Remove unused file.
(configure.ac, Makefile.am): Simplify.
