selftests: forwarding: mirror_lib: skip_hw the VLAN capture
When the VLAN capture is installed on a front panel device and not a
soft device, the packets are counted twice: once in fast path, and once
after they are trapped to the kernel. Resolve the problem by passing
skip_hw flag to vlan_capture_install().
