runqemu: output network configuration

runqemu adds network configuration parameters to the kernel
command line to configure guest networking. This works only
for the images that run with external kernel using qemu -kernel
parameter. It doesn't work for the images that use bootloader
to boot kernel as -kernel parameter is not used and network
configuration is not possible to get.

Added host and guest ip addresses and netmask of tap link
to the runqemu output. This should allow external programs
that execute runqemu to get network configuration.
