py/objmodule: Don't use sys.modules to track a builtin __init__.

Browse Source 
This can lead to duplicate initialisations if a module can be imported
via multiple names, so the module must track this itself anyway.

This reduces code size (diff is -40 bytes), and avoids special treatment of
builtin-modules-with-init with respect to sys.modules. No other builtin
modules get put into sys.modules.

This work was funded through GitHub Sponsors.
