Add two new functions, search_kvmtool_binary(), which, like the name
suggests, searches for the location of the kvmtool binary, and
run_kvmtool(), which runs a test with kvmtool as the VMM.
initrd_create() has also been modified to use the kvmtool syntax for
supplying an initrd, which is --initrd (two dashes instead of the single
dash that qemu uses).
arm/run does not know how to use these functions yet, but this will be
added in a subsequent patch.
