Dockerfile - useradd command invalid while building.

[Flame Sage]

The following command is executed within the following files:
dockerfiles / syncthing / Dockerfile
dockerfiles / syncthing / Dockerfile.supervisord

Had to change the following line

RUN useradd --no-create-home -g users -uid 22000 syncthing

to

RUN useradd --no-create-home -g users -u 22000 syncthing

to fix the follwing error.

useradd: invalid user ID 'id'
The command [/bin/sh -c useradd --no-create-home -g users -uid 22000 syncthing] returned a non-zero code: 3
