Add openbfdd to ptf docker (sonic-net#9488)

Why I did it
To enable test support for BFD-related features, the PTF docker needs to have the proper support for BFD. This PR aims to add BFD support in ptf docker.

How I did it
Clone and build OpenBFDD for PTF docker.

How to verify it
Build locally and verify BFD is supported.
