Subject: [PATCH] Feat: Install `watchdog` as dependency

Install `watchdog` as a dependency into a virtual environment.
This allows to use different versions of Python
without relying on a particular commit of a submodule (the latest
version of `watchdog` (4.0) requires Python 3.8). Run

    make PYTHON=python3.7 USER=1 native-install

to set particular Python version.
