doc: adjust paths in openssl maintenance guide

The path for the crypto files in the `deps/openssl/openssl/`
after running `cd deps/openssl/config && make` has been changed.
The original path `deps/openssl/openssl/crypto/includes/internal/`
now maps to `deps/openssl/openssl/includes/crypto`for the files that
need to be added for the commit.
