kunit: fix up const mis-match in many assert functions

In many kunit assert functions a const pointer is passed to
container_of() and out pops a non-const pointer, which really isn't the
correct thing to do at all.  Fix this up by correctly marking the
casted-to pointer as const to preserve the marking.
