maint: remove empty lines at EOF, but excluding modules/*

Apply syntax rules at home as well as abroad.  Most changes
were induced by running this:
  make srcdir=. _build-aux=build-aux -f top/maint.mk \
    sc_prohibit_empty_lines_at_EOF | grep -v modules/ \
    | xargs perl -pi -0777 -e 's/\n\n+$/\n/'
* cfg.mk (local-checks-to-skip): Enable sc_prohibit_empty_lines_at_EOF.
Exempt modules/* and two binary files.
Also exclude doc/INSTALL*, per request from Bruno Haible.
* doc/regexprops-generic.texi: *Add* a newline at EOF.  There was none.

 	maint: add framework to run syntax-check rules against gnulib sources
 	* cfg.mk: New file, to disable all currently-failing tests.
 	We'll enable them one by one, as they are made to pass.
