The rcutorture scripts currently expect the user to create the tools/testing/selftests/rcutorture/initrd directory. Should the user fail to do this, the kernel build will fail with obscure and confusing error messages. This commit therefore adds explicit checks for the tools/testing/selftests/rcutorture/initrd directory, and if not present, creates one on systems on which dracut is installed. If this directory could not be created, a less obscure error message is emitted and the test is aborted.
