Missing dkms.conf file in system76-driver DKMS source folder causes error

[adamjen]

Had to downgrade from nvidia driver 575 to 570 after upgrading kernal from 6.12 to 6.16 on pop_os

After running:
sudo apt purge system76-driver
sudo apt install system76-driver

...

sudo dkms status
Error! Could not locate dkms.conf file.
File: /var/lib/dkms/system76/1.0.18174310951124.04~8b1da53/source/dkms.conf does not exist.
