[CI] Dockerfiles are updated (cleanup) (#327)

We will use pythonX -m venv ... instead python virtualenv utility.

* [CI] run_tests.sh uses "pythonX -m venv ..."

* [CI] altlinux does not install python virtualenv

* [CI] ubuntu 24_04 does not install python3-virtualenv

* [CI] std/std-all do not install py-virtualenv

* [CI] altlinux dockerfiles are updated (cleanup)

* [CI] fix: ubuntu 24.04 requires python3-venv and build-essential

* [CI] run_tests.sh sets VIRTUAL_ENV_DISABLE_PROMPT=1 (restored)
