ftbfs during kernel build due to dkms changes in lunar

need to revert explicit use of CC= variable, which is now no longer guaranteed to be exported once again.

causes src:linux to FTBFS

--

dkms in jammy and lunar are incompatible with each other, prevent kernel from using dkms during its buildtime to prebuild certain dkms modules. Workaround it by including a fixed copy of dkms script in the kernel, as used at build-time only to produce certain pre-built modules.

possibly dkms regression, testing a fix in the kernel.

This bug was fixed in the package v4l2loopback - 0.12.7-2ubuntu3

---------------
v4l2loopback (0.12.7-2ubuntu3) lunar; urgency=medium

  * Revert to 0.12.7-2ubuntu1, as dkms that unconditionaly exports CC has
    been reverted. Otherwise, currently src:linux FTBFS when trying to
    vendor in this module. LP: #2015279
