tls: remove SecureContext setFreeListLength

This function was introduced in 2684c90
as an internal helper function. The C++ implementation became a no-op in
a57e2f2 when building against OpenSSL
1.1.0 (instead of OpenSSL 1.0.2), and eventually became a no-op in all
supported OpenSSL versions in 970ce14.
Finally, eb20447 removed the only call
site of setFreeListLength (which was already a no-op at that point).
