dockerfile: Create a dedicated syncthing user (#5072)

A dedicated user is necessary to create relative references via
~/<folder> or $HOME/<folder>. Having the syncthing process just running
under a unprivileged UID/GID, will remove the home folder relation and
therefore will result in nonexistent shares after update.
