docs/manual/adding-packages-python.adoc: clarify how _BUILD_OPTS work

Browse Source 
PYTHON_FOO_BUILD_OPTS are passed to the build module call of the package
build, this allows passing options to the python build *backend* by
using the --config-setting= option. setup.py is no longer involved since
even the setuptools backend now used the pep517 build method.

The note about the options being passed to
support/scripts/pyinstaller.py seems to be no longer accurate.
