[OE-core] [PATCH V2 3/3] runqemu-internal: provide more info if a preconfigured tap is used

[Qi.Chen at windriver.com]

From: Chen Qi <Qi.Chen at windriver.com>

We should provide the user more information if a preconfigured tap
is used. This is because the user might have manually set up the tap
interface to be used by other qemu binaries.

So at a minimum, we should let the user know how to make runqemu skip
that tap interface.
