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].
