Some VPS providers preconfigure ufw which can break the
FreedomBox installation process on plain Debian. To
prevent this, make the freedombox package remove ufw.
Tests I made:
1. Enabled ufw on a Debian system
2. Built a custom package with the modification in the
control file
3. Installed the custom packge.
Result: ufw gets removed before the execution of
`update-initramfs: Generating /boot/initrd.img-5.10.0-17-amd64`
