arm64: vdso32: Add DWARF_DEBUG
When building the 32-bit vDSO with LLVM 15 and CONFIG_DEBUG_INFO, there
are the following orphan section warnings:

These are DWARF5 sections, as that is the implicit default version for
clang-14 and newer when just '-g' is used. All DWARF sections are
handled by the DWARF_DEBUG macro from include/asm-generic/vmlinux.lds.h
so use that macro here to fix the warnings regardless of DWARF version.
