LU-8519 build: make SLES use lbuild kernel-devel

SLES %kernel_module_package assume kernel-devel installed
in standard location /usr/src/. However, lbuild extracts
kernel-devel into its location; so we need to change
%kernel_module_package macros to use lbuild's kernel obj

Create a cleanup_rpmmacros to remove the change afterward

Test-parameters: trivial
