Subject: [PATCH] temporal-cli: Fix Darwin builds with sandbox enabled

Unfortunately one of the issues is within a dependency, so have to do
some awkward patching of the go-modules. This patch is pending merge to
the upstream dep and will hopefully eventually trickle down. We do *not*
optionally apply the patch for Darwin only because then we would have a
different hash per system, which seems even more awkward.
