selftests: mptcp: add token for dump_addr
The command dump_addr() of pm_nl_ctl can be used like this in in-kernel PM:
pm_nl_ctl dump
This patch adds token argument for it to support userspace PM:
pm_nl_ctl dump token $token
If 'token $token' is passed to dump_addr(), copy it into the kernel
netlink.
