arm64: elf: Fix allnoconfig kernel build with !ARCH_USE_GNU_PROPERTY 

Commit ab7876a98a ("arm64: elf: Enable BTI at exec based on ELF
program properties") introduced the conditional selection of
ARCH_USE_GNU_PROPERTY if BINFMT_ELF is enabled. With allnoconfig, this
option is no longer selected and the arm64 arch_parse_elf_property()
function clashes with the generic dummy implementation.
