Ross Burton 68ffca3470 runqemu: when tunctl can't be found, say what package builds it
If runqemu is used without actually building any qemu images (i.e. you
downloaded the images) it's likely that qemu-helper-native hasn't been built.
Instead of just saying what command can't be found, tell the user how to solve
their problem.
