[bt][fbl] Remove std::unique_ptr traits from BT stack.
BT was using fbl:: containers, but wanted to use std::unqiue_ptr
instead of fbl::unique_ptr. Because of this, they needed to carry
around their own definition of the pointer traits in order for the
containers to be usable.
Zircon now has support for std::unique_ptr now, however. So the
containers support it by default, and we no longer need extra code up
at this level in order to allow this usage pattern.
Test: Build and runtests on a VIM2
