ppc: Don't set up RTAS for OldWorld Macs

Browse Source 
According to historical device trees, pre-iMac Macs do not seem to
have the /rtas node.

Make /rtas conditional to NewWorld Macs for now, while allowing to
extend this to future CHRP machines.

This means that the ppc-softmmu would by default not have it,
except when using -M mac99. ppc64-softmmu would get it by default.
