[1/3] raisin: introduce TEST_KERNEL and TEST_INITRD

Commit Message

Stefano Stabellini May 23, 2017, 9:43 p.m. UTC

We don't necessarely always want to guess and use the dom0 kernel and
initrd for tests. Introduce two options, TEST_KERNEL and TEST_INITRD,
that allow a user to manually specify which kernel and initrd to use.
