macOS docker compatibility

[juliusknorr]

Since nextcloud/docker-ci#658 we have an arm image available, now trying to run viewer tests with the docker setup I ran into a problem that the docker container ip on macOS is not accessible from the host system without port mapping.

Filing this issue to further investigate options. We probably should try to automatically map to a port and use that instead.

Manual viewer patch to make it work:
