cmd/go: MacOS binaries invalid for eventual Apple Notary [1.12 backport]

[gopherbot]

@ianlancetaylor requested issue #30488 to be considered for backport to the next 1.12 minor release.

@gopherbot please open backport issues

[macetw]

How can I be recognized as the assignee, and with label "NeedsFix?"

[ianlancetaylor]

@gopherbot please add label NeedsFix

[ianlancetaylor]

@gopherbot please assign to macetw

[ianlancetaylor]

Well, at least the label request worked.

[ianlancetaylor]

I can't seem to assign the issue to you anyhow. I wouldn't worry about it.
