py/mpconfig: Enable module delegation if sys needs it.

Browse Source 
Otherwise you can get into the confusing state where e.g. sys.ps1 is
enabled in config (via `MICROPY_PY_SYS_PS1_PS2`) but still doesn't actually
get enabled.

Also verify that the required delegation options are enabled in modsys.c.

This work was funded through GitHub Sponsors.
