What happened?

Describe the bug
recent PR #12801 to [config/configtls] introduced a dependency on OpenSSL/CGO. This is causing the unit tests to fail on MacOS, both locally or in pipeline

Steps to reproduce
run make gotest on MacOS ARM or click to see most recent pipeline CI status: https://github.com/open-telemetry/opentelemetry-collector/actions/runs/14841117409/job/41664078361

What did you expect to see?
tests passing or skipped

What did you see instead?
tests failing

#12801

[jackgopack4]

installing openSSL via brew does not fix the issue, but rather causes the individual tests to fail (e.g. TPM is not supported on this platform) so just adding an openssl dependency for certain platforms in CI won't fix this on its own

TPM is not supporter on Macos anyways - see https://discussions.apple.com/thread/254017151?sortBy=rank
