Remove /etc/network/interfaces and networking service from device packages
Removed the various /etc/network/interfaces
files around and removed from the post-install scripts to enable the networking
service.
This is not necessary anymore since there is now NetworkManager.
device-sony-castor-windy
doesn't require a version bump since the post-install script was not even packaged.
Also removed a duplicate wpa_supplicant
entry in postmarketos-base
's post-install script and cleaned up a bit.
