Create a rudimentary symbol scanning script

We would like to be able to log and audit the symbols we use in openssl
so that we might catch when a new platform symbols is referecned

Add such a script (just on unix platforms for now) that gathers the used
symbols not belonging to libcrypto or libssl, and compare it to a prior
known set of used symbols. Error out if a new symbol is found

Add this script to the ci workflow in CI to capture newly
introduced platform symbols

Fixes #22330
