Disable SSL 3.0 and RC4

The SSL 3.0 protocol and the RC4 cipher are considered insecure and vulnerable to attacks. As such, these two are disabled by default for all Fedora components that use the system-wide crypto policies. This includes gnutls and openssl libraries, and all the applications based on them.

Applications or environments that require SSL 3.0 or RC4 can use update-crypto-policies to globally switch to the LEGACY policy to enable SSL 3.0 and RC4.

Note - All applications that use TLS from NSS are not affected by this change.
