maint.mk: generalize _gl_tight_scope for non-recursive make

* top/maint.mk (_gl_tight_scope): Remove a hard-coded assumption
that *.h would describe additional .h files in the directory
specified by $(_gl_TS_dir).  I.e., add this...
(_gl_TS_other_headers): New variable.

        maint.mk: exempt trailing blanks found in "binary" files
        * top/maint.mk (sc_trailing_blank): Filter out any matches found in
        "binary" files, as reported by grep.  Suggested by Richard W.M. Jones
