runqemu tap device fix

Hello,

n Fedora systems (and likely others), ifconfig returns interface names that end with a colon. Make sure we strip the colon off the tap device name before using it.

This fixes [YOCTO #3028]

I don't have a Fedora system handy, so I asked Tom Zanussi to test this patch, and he confirms it works for him.
