Revert "ipsec: Use the new tunnel API types to add flow label and TTL copy"

This reverts commit c7eaa711f3e25580687df0618e9ca80d3dc85e5f.

Reason for revert: The jenkins job named 'vpp-merge-master-ubuntu1804-x86_64' had 2 IPv6 AH tests fail after the change was merged. Those 2 tests also failed the next time that job ran after an unrelated change was merged.
