Starting with Linux kernel version 6.16, a couple of ovpn-related enum definitions were introduced in the `include/uapi/linux/if_link.h` header. Redefining them in openvpn when they are already present in the system headers can lead to conflicts or build issues.
This commit ensures that enum redefinitions are avoided by conditionally using the existing definitions from the system header when available. This is the port to release/2.6 based on commit 1d3c2b67a73a0aa011c13e62f876d24e49d41df0.
