[PATCH v2 0/3] Fix DTrace on modern kernels and in containers

Hi, I've created three patches for the issues I've encountered when trying to
get DTrace to work in my environments. One environment is on my local computer
running macOS ARM64 using Docker through OrbStack. The other is our Kubernetes
cluster in the cloud. The first two issues are differences in the Linux kernel
compared to what DTrace expects. The third issue is container related.

The OrbStack environment is running version 7.0.11 of the Linux kernel. The
Kubernetes cluster is running 6.12.85.

I'll be honest, the analysis of the issues and the patches are all done by an
AI. I've verified everything manually myself.

Changes since v1:
- Patch 1: also treat BTF_KIND_TYPE_TAG as a transparent modifier in
  dt_btf_real_type_by_id() (per review feedback).

Jacob Carlborg (3):
  libdtrace: resolve BTF type tags transparently
  libdtrace: derive io provider dev_name from the device model
  libdtrace: match BEGIN/END PID in the tracer's own PID namespace
