cmd/cgo/internal/testcarchive: TestManyCalls failures [1.22 backport] #70124
Description
@prattmic requested issue #67566 to be considered for backport to the next 1.22 minor release.
@gopherbot Please backport to 1.22 and 1.23. This is a test-only fix for a flaky test that is regularly flaky on the release branches.
