PR cpp/7263 pragma system_header doesn't suppress warning on LL or ULL constants

Subject: PR cpp/7263 pragma system_header doesn't suppress warning on LL or ULL constants

This fixes part of 7263. A more general fix is difficult because we do
want to test for token->src_loc but we want to print using the
input_location, so using cpp_error_at_location is of no use here.

Bootstrapped and regression tested on x86_64-unknown-linux-gnu with
--enable-languages=all,ada

OK for trunk?
