internal/syscall/unix: use runtime.gostring for Gostring
Under the race detector, checkptr flags uses of unsafe.Slice that
result in slices that straddle multiple Go allocations.
Avoid that scenario by calling existing runtime code.
This fixes a failure on the darwin-.*-race builders introduced in
CL 446178.
