{linux, linux-headers}: split hash file in before and from 6.17

In linux 6.17, the license file LICENSES/preferred/GPL-2.0 was modified.
As a result, also its hash changed, and the hash was duly updated in
commit d6c0f0015b. Of course, this is only
valid for kernel versions from 6.17 - but at the time, we only set
LINUX_LICENSE_FILES for the latest kernel version, not for any other
kernel versions.

Since commit 305a2d91731fade45f35c259cb012bdf17e8dbeb, we also set
LINUX_LICENSE_FILES for all other versions, including e.g. the CIP
versions. Similarly, we now set LICENSE_FILES for all linux-headers
versions. Thus, the hash check of the license file fails for all older
kernel versions.

Fix this by splitting the hash file in two hash files: before-6.17 and
from-6.17. We keep just two hash file rather than a separate one for
each version to limit the number of files that need to be updated when
bumping kernel versions. Create symlinks for all the CIP version in
linux and for all supported versions in linux-headers.

Include the CIP versions as well for linux-headers. They are used when
the kernel is set to the CIP version and linux-headers to
same-as-kernel.
