Revised version of the WIP bpf raw tracepoint support

Based on feedback previous bpf_raw_tracepoint patch.  This patch has the
following changes:

- NEWS entry
- Made behavior more predictable always use the bpf raw tracepoints unless
--compatible=3D4.1 used. if bpf raw tracepoints unavailable error out
- Simplified the logic
- Adjusted bpf.exp to work with the new behavior
- Increased bpf.exp timeout so tracepoint discovery has time to run in the
tests

In a separate patch I have a raw_tracepoint1.stp test that is a
reimplementation of the tracepoint1.stp using the bpf raw tracepoints
arguments.
