[netdata] remove duplicate prefixes in lcoal network data (#7653)

The current implementation attempts to remove existing on-mesh prefix
entry when adding an on-mesh prefix entry with the same prefix. The
same logic exists for external routes. However, the existing code does
not work properly when both on-mesh prefixes and external routes exist
with the same prefix.

This commit simply updates the logic to always remove existing entries
with the same prefix, regardless of whether they are on-mesh prefix or
external route. This is in contrast to trying to keep both on-mesh
prefix and external route with the same prefix simultaneously. There
is no obvious use case for having both the on-mesh prefix and external
route exist at the same time.

OpenThread Build Simulation Docker Language grade: C/C++ Coverage Status


What is OpenThread?

OpenThread released by Google is...

...an open-source implementation of the Thread networking protocol. Google Nest has released OpenThread to make the technology used in Nest products more broadly available to developers to accelerate the development of products for the connected home.

...OS and platform agnostic, with a narrow platform abstraction layer and a small memory footprint, making it highly portable. It supports both system-on-chip (SoC) and network co-processor (NCP) designs.

...a Thread Certified Component, implementing all features defined in the Thread 1.2 specification, including all Thread networking layers (IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, Mesh Routing) and device roles, as well as Border Router support.
