configs/rock_pi_n8: remove defconfig, broken

This defconfig no longer builds:

  https://gitlab.com/buildroot.org/buildroot/-/jobs/11026769867

It has been broken for at least 2 months:

  https://gitlab.com/buildroot.org/buildroot/-/jobs?name=T%3Drock_pi_n8&kind=BUILD

This defconfig was maintained by Suniel Mahesh, but his e-mail at
Amarula is bouncing, so basically this defconfig is unmaintained.

Unless a fix is provided, this defconfig will be removed.

Fixes:
