tests/docker: fix "cc" command to work with podman

Podman requires a little bit of additional magic to the uid mapping
which was already done for the normal RunCommand. We simplify the
logic by pushing it directly into the Docker::run method to avoid
instantiating an extra Docker() object and ensure the CC command
always runs as the current user.
