Connor Shu 0b8fd94975 rcutorture: Automatically create initrd directory
[ Upstream commit 8f15c682ac5a778feb8e343f9057b89beb40d85b ]

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.
