package/directfb-examples: remove package

directfb.org is dead so since commit
89ab2a5a3f4588891ab1e9e76feb8c3f69402d5c (from 2022), we are
downloading from sources.buildroot.net.

Clearly DirectFB 1.x is no longer maintained. A DirectFB 2.x project
is now at https://github.com/directfb2/, but despite an attempt in
August 2024 [1], it still isn't packaged in Buildroot. Therefore it's
time to drop directfb 1.x, which doesn't prevent in the future from
adding directfb 2.x.
