native: fixes for removal of nativenet

dist/tools/wireshark_dissector/README.md

-# RIOT nativenet wireshark dissector
-This allows wireshark to parse packets sent over TAP by RIOT's native port.
-
-## Installation
-Just copy the script ``riot.lua`` to ``$HOME/.wireshark/plugins`` and restart
-Wireshark.
-
-## Usage
-### Debian/Ubuntu
-Ensure that dumpcat is available for you as non-superusers:
-
-```bash
-sudo dpkg-reconfigure wireshark-common
-sudo usermod -a -G wireshark $USER
-```
-
-### Fedora (and possibly others)
-The 'wireshark-devel' package must be installed to run the plugin.
-
-## Configuration
-Depending on what you want to send over the native TAP you might want to change
-the next header dissector. Currently we have included the dissectors for
-IEEE 802.15.4 and 6LoWPAN into the script file, but anything is thinkable.
-Refer to the wireshark manual to get the protocol names, e.g.:
-
-```lua
-    local next_dis = Dissector.get("ipv6")
-```
