Distribute via Snapcraft

[kyleconroy]

Similar to #233, Linux users should be able to install sqlc via snap. I'm less familiar with snaps, so any help from others in the community would be helpful. I'm planning on using GoReleaser as a starting point.

While I haven't figured out how to publish a snap via snapcraft to the snap store (oh snap), I have successfully registered the sqlc name.

I'm planning on following this guide to build the sqlc snap.
