So the point of tar-replacement-native was that it's a *replacement* for
the host tar, so it needs the same name.  If it was to be installed as an
opt-in alternative there's a mechanism for doing that already (see
EXTRANATIVEPATH) but that would break the purpose of tar-replacement-native.

I think for this situation you should show how to enable xattrs for images,
with the caveat that if your host tar isn't suitable the user should
bitbake just tar-replacement-native *first*.
