CI files are updated (#225)

* [CI] work with 'time' is corrected

AltLinux 10 does not support the sequential "time <set_env> coverage run ...".

Because this OS does not has a builtin command 'time' in bash.

https://forum.altlinux.org/index.php?topic=48342.0

We will install 'time' manually and use another command "<set_env> time coverage run ..." that works without problems but it requires to install 'time' on Ubuntu 2024.04, too.

AlpineLinux processes a new command line without any problems.

* [CI] An initization of python virtualenv is simplified

Let's avoid creating useless environment variables.
