[PATCH bpf-next v13 12/14] bpf: export btf_ctx_access to modules.

[thinker.li@gmail.com]

From: Kui-Feng Lee <thinker.li@gmail.com>

The module requires the use of btf_ctx_access() to invoke
bpf_tracing_btf_ctx_access() from a module. This function is valuable for
implementing validation functions that ensure proper access to ctx.
