WIP: Create an unsigned UEFI image. (The configuration file for signed image creation is kept for now as dracut.module/old.dracut.conf.

Makefile: Add generic paths to the install commands, so that tools to build (mostly Debian) package work.

installation/dependencies-installation.sh: Add a script to install the dependencies available in Debian packages.

src/main.*: Add the possibility to give the paths of the fluentbit files (exec, lib, conf...) and the log file as an argument of the program.

Implement the "make; make install" workflow. First working version with "make no-dracut; make install-no-dracut". Needs root privilege for the "install" stage.

Fix a bug in Makefile. Improve the detection test of go in the system in install.sh (may be further improved).

install.sh: Install a specific python version (3.7.12) so that scan-filesystem/cython/Makefile uses it and works everytime.
