selftests/bpf: Add test for bpf_get_branch_snapshot
This test uses bpf_get_branch_snapshot from a fexit program. The test uses
a target function (bpf_testmod_loop_test) and compares the record against
kallsyms. If there isn't enough record matching kallsyms, the test fails.

Reuse module_attach infrastructure to add a new bare tracepoint to check
we can attach to it as a raw tracepoint.
