    python.mk: use gpep517 as build frontend on Python 3.7
    
    Should start allowing PEP-517 packages to build and unbreaking
    circular dependencies, however short a shelf life, due to gpep517's
    almost nonexistant Python dependency tree.
    
    (PyPA build will continue as the preferred build frontend otherwise,
    due to official stewardship, but does not preclude a DEFAULT_VERSIONS
    hook in the future)
