test(openat2): add end-to-end integration coverage for openat2
openat2(2) is the one open-family syscall with a structurally distinct
argument layout: flags/mode live inside the open_how struct (args[2]),
not as a plain int, and args[3] is the struct size. The tracer correctly
reads the path from args[1] and omits flags (ev->flags = -1) rather than
misreading the struct ptr/size, and registers the returned fd->path
mapping via the shared handleOpenExit path. This was verified by
inspection but had no integration scenario, unlike open/openat/creat/
open_by_handle_at.
Add an open-openat2 ioworkload scenario issuing the raw openat2 syscall
(Go has no wrapper and routes Open through openat) and a TestOpenOpenat2
integration test asserting the enter_openat2 tracepoint captures the
path. Verified passing as root.
