kbuild: rpm-pkg: Add (elfutils-devel or libdw-devel) to BuildRequires

The dwarf.h header, which is included by
scripts/gendwarfksyms/gendwarfksyms.h, resides within elfutils-devel
or libdw-devel package.

This portion of the code is compiled under the condition that
CONFIG_GENDWARFKSYMS is enabled.

Consequently, add (elfutils-devel or libdw-devel) to BuildRequires to
prevent unforeseen compilation failures.

Fix follow possible error:
  In file included from scripts/gendwarfksyms/cache.c:6:
  scripts/gendwarfksyms/gendwarfksyms.h:6:10: fatal error: 'dwarf.h' file not found
      6 | #include <dwarf.h>
        |          ^~~~~~~~~
