Add support for multiple 'Architecture' values

This allows architecture to be multivalued. On x86-64 machines, this
could be something like:
    Architecture = x86-64-v3 x86-64

We use the first specified Architecture value in mirrorlist $arch
variable replacement, as this is backwards-compatible and sane.
