[PATCH v3 10/12] automation: create an alpine linux arm64 test job

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Create a test job that starts Xen and Dom0 on QEMU based on the alpine
linux rootfs. Use the Linux kernel and rootfs from the tests-artifacts
containers. Add the Xen tools binaries from the Alpine Linux build job.
