[PATCH] qemurunner.py: support setting slirp host ip address

[Mikko Rapeli <mikko.rapeli@linaro.org>]

By default host side IP address is not set and qemu listens
on all IP addresses on the host machine which is not a good
idea when images have root login enabled without password.
It make sense to listen only on localhost IP address 127.0.0.1 using
config:

QB_SLIRP_OPT = "-netdev user,id=net0,hostfwd=tcp:127.0.0.1:2222-:22"

Support detecting port number from this too.
