util/mkerr.pl: allow module names prefixed with OSSL_ or OPENSSL_
To make sure that our symbols don't clash with other libraries, we
claim the namespaces OSSL and OPENSSL. Because C doesn't provide
namespaces, the only solution is to have them as prefixes on symbols,
thus we allow OSSL_ and OPENSSL_ as prefixes.
These namespace prefixes are optional for the foreseeable future, and
will only be used for new modules as needed on a case by case basis,
until further notice.
For extra safety, there's an added requirement that module names -
apart from the namespace prefix - be at least 2 characters long.
