Update Python build commands for Bookworm

Browse Source 
In Bookworm's version of setuptools, direct calls to setup.py are
deprecated and no longer guaranteed to work. One of the recommended
commands is to use the `build` python package to build packages, and
call it with `python -m build`. This, by default, builds the packages in
a virtualenv to ensure that only the specified dependencies in setup.py
are needed to build the package. This also extends to running tests,
where directly calling `setup.py test` may not work, and the recommended
alternatives are to either call `pytest` directly, or call `tox` or
`nox.` More details are available at [1].

For SONiC's use case, for building python packages, we cannot build all
Python packages in a virtualenv since there are dependencies that we
would have built earlier, and these packages are not pushed to pypi or
any package registry. (There may be a cleaner approach to this, though,
but I'm not aware of it.) For this reason, the `-n` flag is added to not
build the package in a virtualenv.

For testing, `pytest` is now called instead of `setup.py test`.
