rust: vec: impl Default for Vec with any allocator 



The implementation of Default is restricted to only work with kmalloc
vectors for no good reason. This means I have to use

	mem::replace(&mut my_vec, KVVec::new())

in Rust Binder instead of `mem::take(&mut my_vec)`. Thus, expand the
impl of Default to work with any allocator including kvmalloc.
