[PATCH net-next] selftests/net: ensure mptcp is enabled in netns

Some distributions may not enable MPTCP by default. All other MPTCP tests
source mptcp_lib.sh to ensure MPTCP is enabled before testing. However,
the ip_local_port_range test is the only one that does not include this
step.

Let's also ensure MPTCP is enabled in netns for ip_local_port_range so
that it passes on all distributions.
