[Automake-NG] [FYI] maintcheck: remove 'sc_old_includes_vars' check

[Stefano Lattarini]

Now even Automake master explicitly reject uses of the INCLUDES
variable, so that check had become obsolete.  In addition, it
was also causing some false positives.

* maintainer/syntax-checks.mk (sc_old_includes_vars): Remove.
(syntax_check_rules): Adjust.
