Pierre Prinetti 50142f6580 docker: Set the home directory for the user
Before this change, the docker user had home in a directory it had no
permissions on. The inability of creating a cache directory in `$HOME`
prevented npm to work properly.

Additionally, the `node_modules` in the base working directory had its
owner set to root, preventing further changes.

With this change, the `etherpad` user has a home directory.
Additionally, `npm i` is now run by `etherpad` rather than the root
user; this way, it is possible to dynamically change the `node_modules`
content in day 2 operations.

Note that while switching to the `useradd` builtin, a conflict was
discovered with the GID 65534 that was previously used. This change is
changing the `etherpad` user's UID to 5001 to avoid said conflict. As a
consequence, a `chmod -R 5001:5001` must be run prior to attaching
volumes created from previous Etherpad versions.
