This reverts CL 514235. Also reverts CL 518056 which is a followup
fix.
Reason for revert: Proposal #50102 defined an interface that is
too specific to UNIX-y systems and also didn't make much sense.
The proposal is un-accepted, and we'll revisit in Go 1.23.
Fixes (via backport) #65245.
Updates #50102.
