community/dracut: remove network-legacy module
Use the network module instead. The -legacy module depends on ISC dhclient which has been EOL for >2 years and was removed from aports.
If I understand the code correctly, the network module works with conman or network-manager, we can add those to depends if we want to. However, since there is a choice here it might be better to leave it to the user to install them separately.
