Use pwd as a workspace; move sources to src/gopheros and rewrite imports

By setting up pwd as a Go workspace, we can trim import paths from
something like "github.com/achilleasa/gopher-os/kernel" to just
"kernel".

These changes make forking easier and also allows us to move the code to
a different git hosting provider without having to rewrite the imports.
