act, much like CircleCI, doesn't allow us to have easily accessible
volume mounts between the CI system and the Docker host. So, much like
the build of the updater, the linter now no longer requires volume
mounts to lint ebuilds.
This implementation is decently ineffecient and will be improved over
time.
Adds an automatic updater to handle updating ebuilds in this repository
based on the latest version available on the remote.
Also puts `elint` in this repo since I've been working on this one more
than the former.
