arm64: vdso32: Shuffle .ARM.exidx section above ELF_DETAILS
When building the 32-bit vDSO after commit 5c4fb60816ea ("arm64: vdso32:
add ARM.exidx* sections"), ld.lld 11 fails to link:
ld.lld: error: could not allocate headers
ld.lld: error: unable to place section .text at file offset [0x2A0, 0xBB1]; check your linker script for overflows
ld.lld: error: unable to place section .comment at file offset [0xBB2, 0xC8A]; check your linker script for overflows
ld.lld: error: unable to place section .symtab at file offset [0xC8C, 0xE0B]; check your linker script for overflows
ld.lld: error: unable to place section .strtab at file offset [0xE0C, 0xF1C]; check your linker script for overflows
ld.lld: error: unable to place section .shstrtab at file offset [0xF1D, 0xFAA]; check your linker script for overflows
ld.lld: error: section .ARM.exidx file range overlaps with .hash

>>> .ARM.attributes range is [0xD0, 0x10B]
ld.lld: error: section .ARM.attributes file range overlaps with .dynsym
>>> .ARM.attributes range is [0xD0, 0x10B]
>>> .dynsym range is [0xE4, 0x133]
ld.lld: error: section .ARM.exidx virtual address range overlaps with .hash
>>> .ARM.exidx range is [0x90, 0xCF]
>>> .hash range is [0xB4, 0xE3]
ld.lld: error: section .ARM.exidx load address range overlaps with .hash
>>> .ARM.exidx range is [0x90, 0xCF]
>>> .hash range is [0xB4, 0xE3]
This was fixed in ld.lld 12 with a change to match GNU ld's semantics of
placing non-SHF_ALLOC sections after SHF_ALLOC sections.
To workaround this issue, move the .ARM.exidx section before the
.comment, .symtab, .strtab, and .shstrtab sections (ELF_DETAILS) so that
those sections remain contiguous with the .ARM.attributes section.
