Update bundled go-ipfs version for existing CLI install

[walkah]

The CLI fetches a version of go-ipfs during fission setup ... however, we don't check or update the bundled go-ipfs at other times. This means that even if you update the CLI version, it will use the go-ipfs version from the initial setup.

We already do a periodic check for the CLI version - I propose we check the current go-ipfs version on the same cycle (and potentially update).

Workaround: running fission setup will download the version to match.
