[FYI 6/8] java coverage: try to build and run a java program

[Stefano Lattarini]

* tests/java-compile-run-flat.test: New test, try to build and run
a "UNIX-style" java program (complete with wrapper shell script
and the like) with a "flat" source-tree setup (i.e., everything in
the top-level directory).
* tests/java-compile-nested.test: Likewise, but using a more
typical "nested" source-tree setup.
* tests/Makefile.am (TESTS): Update.
