runqemu: Add network bridge support
Qemu supports attaching the virtual machine to an existing network bridge interface via the qemu-bridge-helper program (as long as the system is correctly configured to give the user permissions). Add support for runqemu to do this also via the "bridge=<INTERFACE>" argument. Note that for this to work correctly, the host qemu-bridge-helper must be used, not the one that might have been built by qemu-native. In order for qemu to correctly find this program, a qemu-oe-bridge-helper program has been added to qemu-helper-native, and runqemu will use this helper as the bridge helper. The helper will look for the host qemu-bridge-helper first by looking in the QEMU_BRIDGE_HELPER environment variable, then by search common paths where the helper is installed.
