Add latest-linux.yml to release

[matthewboman]

I tried following the docs to install, but after running npm start I got the following error:

Cannot check for updates: Error: Cannot find latest-linux.yml in the latest release artifacts
(https://github.com/thenewinquiry/bailbloc/releases/download/v1.1.4/latest-linux.yml): 
HttpError: 404 Not Found

It seems like it's trying to get 'latest-linux.yml' but all I see listed on the release are 'latest.yml' and 'latest-mac.yml'

Linux Mint 17.3, Node 8.0.0, NPM 5.4.2

Looks like the last linux build available is 1.0.16 (bailbloc-1.0.16-x86_64.AppImage). If the update error prevents it from running at all (oops), consider grabbing a copy of xmrig (the built-in one is fine) and running it manually with https://gist.github.com/ferristseng/1d76ee8518724cd8f83772380c5c36cb for now.

a8b30c7 should be able to fix the problem for future builds.
