Internal telemetry breaks compiled binaries on unsupported OSes #14307

What happened?
Describe the bug
Custom compiled binaries for AIX (and other unsupported OSes) do not start. The following error is thrown when starting the collector:
Error: failed to register process metrics: not implemented yet
2025/12/17 13:32:42 collector server run finished with error: failed to register process metrics: not implemented yetThe root cause is that the gopsutil library does not support AIX, however setting the following in the service config should disable internal telemetry and suppress this error:
telemetry:
metrics:
level: noneThis appears to be a regression of this change, affecting all releases starting with 0.136.0.
Steps to reproduce
Compile a recent version of the OTel collector (anything 0.136.0 or later) with GOOS=aix GOARCH=ppc64. I used the following minimal builder config to avoid other compatibility issues while testing:

What did you expect to see?
Setting service.telemetry.metrics.level: none should prevent the failed to register process metrics: not implemented yet error message and allow the collector to start normally.
What did you see instead?
The collector fails to start with the following output:

Additional context
Because this is a regression, there is a previous closed issue reported: #12098
Issue was fixed in this PR.
Fix is present in service.go v0.135.0, missing in v0.136.0.
