Trace.h: explicitly use global namespace
Imagine an AIDL file:
package android.foo;
interface IFoo {}
The AIDL C++ backend will generate classes like "::android::foo::IFoo".
In order to avoid ODR conflict, the NDK (Stable C) backend linking
against libbinder_ndk puts everything under the "::aidl" namespace. So,
we have "::aidl::android::foo::IFoo". When using ScopedTrace in a class
implementing a class from this backend, there is this problem.
