Subject: [PATCH] docs/INSTALL.md: update Go installation options for Linux

In this commit, we modify the Linux installation instructions to use the
pre-built archives rather than install from the ppa. We do this as
typically the ppa lags behind the latest releases, and also by
downloading it in this new manner, we're able to verify the sha256 sum
of the installed Go release.
