openssl: correct license comment

The comment here stated that openssl is dual-licensed, but that would mean that either of the two licenses could be used which is *not* the case [1]. However LICENSE = "openssl" *is* correct because in OE that maps to a generic license file which includes both licenses, which makes sense because there isn't really any such thing as OpenSSL that would be covered by the "OpenSSL license" and not the "SSLeay license". Correct the comment to avoid any confusion.
