On Arm64 linux_elf_fixup() is noop, as it do the stack fixup (room for argc) in the linux_copyout_strings().

So, old 32-bit binaries that knows only 32-bit time_t uses the old value of the constant, and binaries that knows 64-bit time_t uses the new constant. To determine what size of time_t type is expected by the user-space, store requested value (SO_TIMESTAMP) in the process emuldata structure.
