delegate_to: 127.0.0.1 in install.yml breaks on multi-arch provision

[queekusme]

I have 2x raspberry pis in my local cluster I am installing consul on. (Pi2, and a Pi4). The 2 Pis don't share the same arch as the 2 is 32bit and the 4 is 64 bit.

Whilst installing I found that my 2 was failing to install the 32 bit binary as delegate_to only runs once and seems to be pulling the values for the 4.

I can see the benefits of running something only once however in this case, this is not desired functionality.
