Ok, so with 4.7 there is:

but with 4.8 it is:

For some reason, the same connect() call is failing with 4.8.
geteuid() returning 0 confirms it's running as root. The difference in
the bind() call is expected, that's was one of the changes made in
4.8, but I'm not sure how could that impact the connect() call.
I still suspect an AppArmor issue. Where did you get the 4.8 package?
On https://launchpad.net/ubuntu/+source/chrony I see the latest
version that Ubuntu has is 4.7.
