Vyacheslav Egorov 939cdfbfcd [vm] Move bin/lockers.h to platform/lockers.h
We have to place these classes into a platform namespace to avoid
conflicts with vm/lockers.h.

To avoid changes to files in bin we simply change bin/lockers.h
to introduce bin::{Monitor,Mutex}Locker aliases for
platform::{Monitor,Mutex}Locker.
