Subject: [PATCH] udhcpsnoop: import package from TIP

Import the udhcpsnoop package from the TIP feed.

The original Makefile in TIP repo spcifies GPL-2.0 as the PKG_LICENSE.
However this is a mistake, as the SPDX headers of the repos source files
all specify BSD-3-Clause as their license.

See https://github.com/Telecominfraproject/wlan-ap/blob/uCentral-trunk/feeds/ucentral/udhcpsnoop/Makefile
