Calamares uses the settings as per /etc/calamares/settings.conf with the installer. These settings consist of all the important modules that are to be loaded from the launch of the installer till the end. The order in which these modules should be loaded is also important.

• Fix the ordering of the modules as per they'll be needed in the installation process following Debian's settings procedure.
• Add the missing modules because of which the installation with EFI system partitions fails (introduced in commit 08d5ee8d).
• Add missing mount-media-chroot module to calamares-modules to complete the desired installation procedure.
• Use the bootloader EFI configuration script from Debian upstream with slight modifications as follows:
  1. apt update before installing packages
  2. Install grub-efi package
  3. Remove unneeded cryptsetup and keyutils packages

Side-effects: None known so far

Tested: OK
