macros.kmp: avoid error in latest_kernel when no kernel is installed

If no kernel-devel packages are installed (this is possible, for example,
during SRPM generation in an isolated environment), no output would be
generated for latest_kernel macro, which would lead to an error (since
an RPM macro can't have an empty definition).  Append %nil to the input
of the "head" command to avoid this situation.

* macros.kmp (kernel_module_package): Feed additional line with %nil
to the input of head command in the latest_kernel macro definition.
