The primary change in this release for runc is that libpathrs's behaviour when the cached ProcfsHandle fd is closed from underneath it is now more graceful (previously this would cause panics on the error path). This is a bit of an unusual program state, but it is something we do in runc before we exec the user binary. Commit 1056e68 ("libct: don't reset selinux labels on init error path") eliminated one cause of such panics, but this should completely resolve the issue. It also includes some key fixes when building with Clang or when distributions re-generate the libpathrs <pathrs.h> header as part of their build process which go-pathrs then consumes.

This independently fixes #5438.
