[PATCH 1/2] linux-custom.inc: drop library dependencies from kernel headers

[PATCH 1/2] linux-custom.inc: drop library dependencies from kernel headers

['Quirin Gylstorff' via isar-users]

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

The upstream headers do not have dependencies to the runtime libraries.
The ${shlibs:Depends} macro will correctly generate the necessary
dependencies.

libssl is only used in extract-cert which is necessary during the kerneln build
if CONFIG_SYSTEM_TRUSTED_KEYRING is enabled.
This config element is not necessary for the module build
and is therefore removed from the kbuild packages.

From: Quirin Gylstorff <quirin.gylstorff@siemens.com>

The debian macro is ${shlibs:Depends} to generate the shared library
dependencies

Patch ordering: Fix the shlibs thing in patch 2 first so that you can
safely drop the THEN no longer needed header deps.
