Running "make clean" in some directories can break "make test" in
others. That notably happens by running clean somewhere in or below
$(TOPDIR)/src/python, which removes __init__.py files potentially needed
by unit and integration tests in $(TOPDIR)/test.
This commit makes the failure easily visible by introducing the notion
of "testabiltity" - if the tree is not testable, "make test" logs
exactly that in a clear error message and gives up.
Makefiles which need to check "testability" can use it as a
prerequisite. This commit does that with py-run.mk and jw-py-test.mk.
Testability is asserted by running "make", "make all" or "make test"
from $(TOPDIR). A successful toplevel build coincides with testability,
and leaves a $(TOPDIR)/dirs-all.done behind, which is why that file is
the perfect testability marker.
It is automatically created by a toplevel build and cleared by using the
"invalidate-testability" prerequisite. This commit makes target "clean"
depend on it in py-mod.mk. To be extended to other use cases / makefile
snippets as needed.

local/src is a janware-specific path, remove it from App and defs.mk.
It's still in pkg.sh as a safety measure. Will have to go, too, but
is kept in for now until further audit.

Add include file to provide some definitions for a first integration
test suite. It provides the shared make variables, most notably
TEST_CMD_LINE as handy default for running jw-pkg.py.
