This patch alongwith commit 7b6a3ad7 close bugzilla entry: https://bugs.hamaralinux.org/show_bug.cgi?id=423

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.

gnome-system-tools was showing a warning about Hamara Sugam being an
unsupported platform. g-s-t checks for the presence for debian_version
file in /etc to pass a distro for Debian or Debian-based. Since this
file was not present in Hamara Sugam, checks were failing and the
warning showed up.

Add an empty debian_version file in /etc to avoid any warnings.
