runtime: intermittent os/exec.Command.Start() Hang on Darwin in Presence of "plugin" Package [1.16 backport]

[gopherbot]

@cherrymui requested issue #38824 to be considered for backport to the next 1.16 minor release.

@gopherbot please backport this to previous releases. This can cause program that uses plugins to hang on macOS.

Change https://golang.org/cl/373095 mentions this issue: [release-branch.go1.16] cmd/link: force eager binding when using plugins on darwin

[cagedmantis]

This is a serious issue without a workaround.

Closed by merging 5ef9566 to release-branch.go1.16.
