According to https://lwn.net/Articles/542629/ , Linux introduced SO_REUSEPORT socket option in 3.9 release. We should handle this gracefully for those kernel version <3.9

[James Page (james-page)]

Also causing issues on older package builders in launchpad which are only running 3.2.0 kernels.

Raising a bug task for Ubuntu so we can fixup kilo release.

[James Page (james-page)]

[Impact]
Use of SO_REUSEPORT causes test failures on older distro builders (3.2.0 kernel)

[Test Case]
Build designate package in distro.

[Regression Potential]
Minimal - opportunistic use of feature if allowed.
