Subject: [PATCH 07/11] alpine: fix arch and enable mips64 and s390x

Fix detecion of the alpine architecture name.

This allows us to create both armv7 and armhf (armv6) containers on an
aarch64 host. eg.

  lxc-create -t alpine a1 -- -a armv7

It also allows us to create mips64 and s390x containers, and potentially
new architectures in the future.
