package/pkg-python.mk: migrate setuptools to pep517

Now that setuptools and its dependencies are using pep517 we can
migrate the setuptools infrastructure itself to use the pep517
build frontend.

As part of this we need to migrate the all python packages using
_BUILD_OPTS to the new config settings format used by the pep517
build frontend.

We need to use a setup.cfg file to pass the pg_config path when
building python-psycopg2 as this package needs the pg_config
path for all internal build stages while -C--build-option= only
passes the flag to the internal bdist_wheel stage.

Use new setup type variables to define setup type specific
dependencies instead of using the conditional block.

In python-m2crypto, the --openssl option is a build_ext option
so we need to add -C--build-option build_ext in front of it.

We also need to set --skip-dependency-check for the following
packages which specify build dependencies that are not actually
required:
 - python-lxml
 - python-matplotlib
 - python-msgpack
 - python-pymupdf
 - python-uvloop
 - python-wsaccel
