grep: mark unused parmaeters in pcre fallbacks
When USE_LIBPCRE2 is not defined, we compile several noop fallbacks. These need to have their parameters annotated to avoid -Wunused-parameter warnings (and obviously we cannot remove the parameters, since the functions must match the non-fallback versions).
