ip_tunnel: fix building with NET_IP_TUNNEL=m
When af_mpls is built-in but the tunnel support is a module,
we get a link failure:
net/mpls/af_mpls.o: In function `mpls_init':
af_mpls.c:(.init.text+0xdc): undefined reference to `ip_tunnel_encap_add_ops'
This adds a Kconfig statement to prevent the broken
configuration and force mpls to be a module as well in
this case.
