maint.mk: avoid sc_prohibit_always-defined_macros failure in coreutils

* top/maint.mk (gl_extract_significant_defines_): Now that
SA_RESETHAND and SA_RESTART are #defined (albeit conditionally) in
gnulib/lib/signal.in.h, and now that we recommend to
define-if-undefined those two symbols in application code,
we must filter them out of the "significant" list.
This avoids a "make syntax-check" failure in coreutils.
