[PATCH v2] scripts: Do not strip .rela.dyn section

[Alexandre Ghiti]

riscv uses the .rela.dyn section to relocate the kernel at runtime but
that section is stripped from vmlinux. That prevents kexec to
successfully load vmlinux since it does not contain the relocations info
needed.

Fixes: 71d815bf5dfd ("kbuild: Strip runtime const RELA sections correctly")
