tune-core2: Update qemu cpu to supported model

From: Simone Weiß <simone.p.weiss@posteo.com>

Fixes [YOCTO #12388]

QEMUs documentation does recommend to not use n270 and core2duo as
an argument to -cpu anymore. Update therefore the QEMU cpu option for
the core2duo tune to Nehalam. Tested it locally with QEMU and KVM.

Please provide a link to the documentation in the commit message, and not
just the claim.
