meta-evb-nuvoton: add symlinks for machine-conf for setup

The 'setup' script looks for machine config files being present
to know that the meta-layer contains a valid machine for OpenBMC.
The nuvoton EVBs are split between meta-nuvoton for the base support
and meta-evb-nuvoton for "EVB on Phosphor" support.

Add symlinks for the machine config files from meta-nuvoton into
meta-evb-nuvoton so that setup recognizes them as valid machines, but
using the phosphor layers.
