tls: revert disable RC4 and cipher lists changes

This reverts commit 67d9a562.

This commit actually reverts both
67d9a562 and
02a549ed (both related to ciphers list
changes). It does it in one commit because reverting
02a549ed results in an empty commit.

These changes are not yet ready to be released, and before they are we
want to be able to publish new releases. We're reverting them so that we
can submit a new PR that will contain all these changes plus what's
necessary to be able to land them properly.
