zaius: enable distro feature to support MAC2

Enable the distro feature phosphor-aspeednic-use-mac2
to support MAC2

This solution is not desirable but it works for now,
For details please refer to
https://gerrit.openbmc-project.xyz/c/openbmc/meta-phosphor/+/23415

Noted that this changed local.conf.sample, which means you need to
modify the build/conf/local.conf accordingly

Tested: devtool modify u-boot and saw the aspeednic patch is applied.
