test: clear stale RADIX handshake injection selectors

The handshake injection helpers share radix_fault with earlier scripts
but left its selector words unchanged. script_68 leaves word0 set to 1,
which selects CertificateRequest. script_69 installs the same callback
before it sets word0 to 2 for KeyUpdate. A session ticket generated in
that interval can trigger the previous script's fault and close the
connection before the intended KeyUpdate injection.

Clear both selector words in the handshake injection setup paths, as
the plaintext injection setup already does. Request a normal session
ticket in script_69 before arming its fault, so the test exercises the
interval where an inherited selector caused the unexpected close.
Keep the expected KeyUpdate close code unchanged.
