Ryan Zuklie 657482041f Add a test BPF program with a ring buffer. 
This adds an example BPF program with a ring buffer. The program using
the ring buffer is limited to kernel versions 5.8 and above (the same as
the ringbuffer internally). The program is marked critical to ensure
that the platform can support ringbuffers in the bpfloader.

This is only done for userdebug builds currently since tests that use it
can only be run in userdebug builds and statically allocates a 4KB ring
buffer.

Bug: 246985031
Test: build and flash on 4.19 and 5.10
