Update Go to 1.10.5 to pick up Mojave fix (#10221)
Update Go to 1.10.5 to pick up Mojave fix (#10221)

There is an architecture issue with Mojave + 1.10.3, most
succinctly discussed here: https://github.com/cloudflare/cfssl/issues/899

I looked at the issue almost zero percent, and just eagerly updated to
the purported fixed version

I picked 1.10.5 over the closest upgrade of 1.10.4 because the 1.10.5 is supported
by upstream Pants and requires no packaging or uploading from us internally.
