openssl_1.0: drop leading "-" from no-ssl3 config option

openssl_1.0: drop leading "-" from no-ssl3 config option

Although passing -no-ssl3 works, comments in the openssl Configure
script suggest doing so isn't really correct:

  s /^-no-/no-/; # some people just can't read the instructions

The documented way to pass no-<cipher> config options is without a
leading "-"
