scripts: Do not strip .rela.dyn section

Browse source 
The .rela.dyn section contains runtime relocations and is only emitted
for a relocatable kernel.

riscv uses this 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: 559d1e45a1 ("riscv: Use --emit-relocs in order to move .rela.dyn in init")
