maint: clean up the output from syntax-check rules

* cfg.mk (sc_tight_scope): Pass the -s (silent) flag to `make`
so that it doesn't report about calling sub makes.
(sc_check-AUTHORS): Likewise.
(sc_strftime_check): Don't display stderr from `info`.
* src/Makefile.am (sc_tight_scope): Don't annotate with "GEN".
(sc_check-AUTHORS): Likewise.
