tests: warnings in the 'obsolete' category: fix spurious failure

* t/warnings-obsolete-default.sh: $(INCLUDES) is no longer supported
in any way by Automake-NG, to a point that its definition will just
be ignored, but cause no warning; so, instead, use the two-argument
invocation form of AM_INIT_AUTOMAKE to elicit warnings in the 'obsolete'
category.
