This adds pep517(needed for flit-core to build itself) and flit python
package types.
We need to add an installer script and pass it appropriate options for
installing pep517 wheels generated by python-pypa-build during the
build stage. Unfortunately it seems pep517 does not support builds
without using the wheel format.
We also need to add a patch fixing the version parser in flit-core.

[Arnout:
- fix indentation in pkg-python.mk (tabs, not spaces);
- use the new _CMD variables instead of duplicating the entire _CMDS
definitions;
- no need to filter dependencies (they're not self-referencing);
- _NEEDS_HOST_PYTHON no longer exists;
- host-python-pypa-build gets added to DEPENDENCIES automatically.
