runqemu: allow bypassing of network setup

Browse Source 
At present it is silently assumed all QEMU machines support networking.
As a consequence, one cannot run QEMUs without network emulation
using "runqemu".
This patch allows bypassing any network setup providing the qemuboot.conf
file contains:

    qb_net = none
