py/mpconfig: Enable the sys module at all feature levels by default.

Browse source 
This is a pretty fundamental module, and even minimal ports like unix and
zephyr minimal have it enabled.  So, enabled it by default at the lowest
feature level.

Most things in the `sys` module are configurable, and off by default, so it
shouldn't add too much to ports that don't already have it enabled (which
is just the minimal port).

Also note that `sys` is still disabled on the bare-arm port, to keep that
ultra minimal.  It means we now have bare-arm without `sys` and the minimal
port with `sys`.  That will allow different code size comparisons if/when
new `sys` features are added.
