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.

Add a sub-script to create and set the keys in Secure Boot. Modify install.sh to make it call the new sub-script.

Apply previous changes to uefi.main.pyx. Change the begining of the file-system walk from "." to "/".

Fix a segmentation fault due to the way the mac address was get. Note that the program does not send the mac address anymore.

Add a wait() call in main to improve fluent-bit behavior.
(Note: first working version with UEFI.)

Improve first working version.
(Note: last version before the first test on the capri002.)

Add more automation in overall and in install.sh.

Add project scan-filesystem (from Xavier Thompson's gitlab) which implements a filesystem scanner.
Modify Makefile and call to a script allow to compile it without linking it from Python functions.
Modify dracut.module/Makefile to compile scan-filesystem instead of Leo's Rust code.

1. add tests, but how?
2. use command to add key in bios
3. set bios password
4. how to check network if have no dhcp
...

git wont keep track of empty folders, therefore create it using the
Makefile.

The module is unsafe because it collects metadata while being
writable for files on the same system; It therefore cannot be
relied upon for security purposes. It will however allow to use
the agent for purposes of better system changes transparency where
malicious changes are not expected.

UEFI standard asks that UEFI applications are located in an
/EFI/vendor folder. We therefore place them within /EFI/Nexedi
inside the EFI System Partition.
