NFSv4: Fix nfs4_init_uniform_client_string for net namespaces

Commit 6f2ea7f2a (NFS: Add nfs4_unique_id boot parameter) introduces a
boot parameter that allows client administrators to set a string
identifier for use by the EXCHANGE_ID and SETCLIENTID arguments in order
to make them more globally unique.

Unfortunately, that uniquifier is no longer globally unique in the presence
of net namespaces, since each container expects to be able to set up their
own lease when mounting a new NFSv4/4.1 partition.
The fix is to add back in the container-specific hostname in addition to
the unique id.
