tests: a test about warnings in category 'obsolete' was failing spuriously

* t/warnings-obsolete-default.sh : After our removal of $(INCLUDES)
support, this test has been spuriously failing because it was assuming
that a definition of the INCLUDES make variable only caused a warning
rather than a fatal error.  Fix it to use a definition of the newly
obsolescent ACLOCAL_AMFLAGS make variable.
