Because mkosi needs to run as root, we also need to make sure we can enter the root password when the editor
plugin tries to run the mkosi-clangd.sh script. To be able to enter the root password in non-interactive
scripts, we use an askpass provider. This is a program that sudo will launch if it detects it's being
