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.
