doc: document the new opt_legacy_okay() function's behaviour

commit 09b430cd87bc3b018fb97879eb6a2ea540c8e923
Author: Pauli <pa...@openssl.org>
Date: Thu Jul 8 11:25:11 2021 +1000
app: add library context and propq arguments to opt_md() and opt_cipher()
Also avoid calling EVP_get_XXXbyname() if legacy paths aren't allowed.

commit ff215713655e721be505cc884aed5d1230c7759e
Author: Pauli <pa...@openssl.org>
Date: Thu Jul 8 11:24:05 2021 +1000
apps: add a function opt_legacy_okay() that indicates if legacy paths are
permitted or not
By default they are. However, if a provider, provider path or a property
query has been specified
they are not. Likewise, if a library context or a property query has been
specified by the command, they are not.

Replacing rather than fixing:

Since that claims to fix another:

If there were no parameters, it will point to the NULL that is

+The opt_legacy_okay() function returns true if no options have been
