Fix expected output for uid/uid after base image change

[mkralik3]

error from the latest builds:

  privileged_pods_test.go:84:    FAILURE: UID, GID and Groups were not changed; expected to find the string 'uid=1002(1002) gid=1002 groups=1002' in the output, but it wasn't found; full output:
        uid=1002(1002) gid=1002(1002) groups=1002(1002)

Probably the output of id command was changed after the proxy base image upgrade from uid=1002(1002) gid=1002 groups=1002 to uid=1002(1002) gid=1002(1002) groups=1002(1002)
