nut: actually update to 2.8.0

The previous attempt at updating nut forgot to change the fod hash for the source code.
Actually updating to 2.8.0 required some changes to dependencies and the patch
for nut-scanner.

We no longer need --without-hal because HAL support was removed as far
back as verison 2.7.2.
