compat api: use network mode bridge as default

Browse Source 
For better docker compatibility we should use the bridge network mode as
default for rootless. This was already done previously but commit
535818414c2a introduced this regression in v4.0.

Since the apiv2 test are only run rootful we cannot catch this problem
in CI.
