Cannot open display when running with a user space switch and innamespace

See original GitHub issue

When running mininet with a userspace switch and with the --innamespace argument, X forwarding stops working!

For example, wireshark returns the following error:

** (wireshark:6096): WARNING **: Could not open X display
error: XDG_RUNTIME_DIR not set in the environment.

(wireshark:6096): Gtk-WARNING **: cannot open display: localhost:11.0

xterm return a similar error.

How to reproduce:

sudo mn --topo single,3 --mac --switch user --controller remote --innamespace
