kbuild: always create intermediate vmlinux.unstripped

Generate the intermediate vmlinux.unstripped regardless of
CONFIG_ARCH_VMLINUX_NEEDS_RELOCS.

If CONFIG_ARCH_VMLINUX_NEEDS_RELOCS is unset, vmlinux.unstripped and
vmlinux are identiacal.

This simplifies the build rule, and allows to strip more sections
by adding them to remove-section-y.
