Dockerfile: remove spdx-licenses-list

Including a copy in void-packages turned out better solution.
Grep in image don't have required perl regexps, and getting
one that have make linting slower by order of magnitude.
Even if it was already there, simply using image is
unnecessarily slower.

This reverts commit 163a923.
