[PATCH] kexec-tools: purgatory: fix build on `binutils-2.42`

[Sergei Trofimovich]

`binutils-2.42` introduced stricter checks on what `.arch` can be used
in 64-bit mode and started failing the build as:

    $ as-2.42 --64 -o entry32-16-debug.o entry32-16-debug.s
    purgatory/arch/i386/entry32-16-debug.S: Assembler messages:
    purgatory/arch/i386/entry32-16-debug.S:28: Error: 64bit mode not supported on `i386'.

The change moves `.code32` before `.arch 386` as suggested in
https://sourceware.org/PR31319
