[kvm-unit-tests PATCH 4/6] gitlab-ci: Move check-kerneldoc test out of the centos test

[Nicholas Piggin <npiggin@gmail.com>]

This creates a new lightweight (alpine) kerneldoc check, based
on the QEMU static checking jobs.

The aim is to decouple the test build and run jobs on different
platforms from the static checker images, so one can be adjusted
without affecting the other.
