LU-12899 build: rhel8 not install kernel-rpm-macros

On RHEL8 kmodtool and kernel_module_package_buildreqs are not
installed with kernel-devel.

kernel_module_package_buildreqs is defined in kernel-rpm-marcos.
If kernel-rpm-macros is not installed, the Lustre RPM build will
report:
"Dependency tokens must begin with alpha-numeric, '_' or '/':
BuildRequires: %kernel_module_package_buildreqs"

This patch helps the developer understanding the detailed
information for the required packages when kernel-rpm-macros is
not installed.
