[Buildroot] [PATCH 2/2] configs/lego_ev3_defconfig: enable brickd by default

[David Lechner]

This enables the brickd package by default on LEGO MINDSTORM EV3. This
program is important because it shuts down the system on low battery.
Without this, rechargeable batteries could be damaged.

I've applied, after fixing one dependency issue, see below.

Both libglib2 and libgudev have a depends on BR2_USE_MMU, so it should
have been replicated here.

And here.

I said, I fixed that up when applying.

Thanks!
