[PATCH container 3/3] setup: make the architecture fall back to amd64 for empty strings

[Daniel Kral <d.kral@proxmox.com>]

Otherwise, if the underlying detect_architecture(...) method returns any
false value, the return value of the call to protected_call(...) will
return an empty string.

This sets the architecture to an empty string and will make the
container fail to start.
