This removes the user and group juggling, which would fail when given
for example a PGID that already existed as the "syncthing" group could
then not be created with that PGID. It's not reasonable to expect the
user to know which group/user names/IDs are already present in the
Docker image.
Instead we now just launch under the specified IDs, while manually
setting the HOME env var to give us a home directory - the only thing we
needed the user entry for anyway.
Also updates to Go 1.11 and building without upgrades instead of
disabling by env var.
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.

Allows for configuring the UID and GID Syncthing runs as in the container. Uses su-exec from the Alpine repos to accomplish this. Addition of su-exec results in <2MB increase in image size.
Added EXPOSE to Dockerfile. this way these ports will show up in docker GUIs like cockpit.
Added VOLUME parameter, this renders creating the folder (/var/syncthing) obsolete.
