    tune-core2: use n270 instead of core2duo
    
    Fixes warnings in builds using core2-32 tune:
    
    warning: TCG doesn't support requested feature: CPUID.80000001H:EDX.syscall [bit 11]
    warning: TCG doesn't support requested feature: CPUID.80000001H:EDX.lm [bit 29]
    
    when executing postinsts using qemu-i386.
    
    i386 target doesn't enable CPUID_EXT2_SYSCALL and CPUID_EXT2_LM [1]
    while cpu choice of core2duo that we use for core2-32 TUNE does [2].
    Use n270 cpu instead to use with qemu which supports SSSE3 and doesn't
    have these bits enabled [3].

    [2] https://github.com/qemu/qemu/blob/master/target/i386/cpu.c#L1439
    [3] https://github.com/qemu/qemu/blob/master/target/i386/cpu.c#L1603
    
    Fixes [YOCTO #12916]
