I couldn't care less about bpf, this is about the kernel API.

What I mean is that your new probe_kernel_read_strict and
strncpy_from_unsafe_strict helpers are good and useful.  But for this
to actually make sense we need to get rid of the non-strict versions,
and we also need to get rid of some of the weak alias magic.
