x/telemetry: tests fail for openbsd

[pjweinb]

This is a placeholder to note that in the telemetry package, two tests are skipped if runtime.GOOS is openbsd.

Here is a CL with failing tests: https://go.dev/cl/589939

Additional tests to fix this support of x/telemetry on OpenBSD.

• Clone x/telemetry sources from https://go.googlesource.com/telemetry

• OK Build telemetry on OpenBSD/amd64 (current version) with Go 1.23.1 (package/port go installed for OpenBSD/amd64)

• Patch internal/telemetry/dir.go to enable OpenBSD platform:

Full log tests failure in internal/counter with go test: telemetry-test.log

After some analysis/debug, it seems than there is an issue with:

• Parse function in internal/counter/parse.go
• ReadStack function in internal/counter/stackcounter.go
