Update run to change Path

Change /etc/services.d/code-server/run to /etc/s6-overlay/s6-rc.d/svc-code-server/run
This allows the file to correctly change the path environment variable during the goland package add process. Currently when using the /etc/services.d/code-server/run path it results in an error and the path environment variable unchanged. 
I forked this repo, ran a build image to my own docker repo and was able to test that this change does indeed allow the file to change the environment variable correctly.
