build: Add stub _get_thread_info() needed by support/Referenceable.cpp

Browse Source 
This is a step towards fixing #10042.

When DEBUG is set BReferenceable::~BReferenceable() performs some checks
ensuring that the object is destroyed correctly. These checks require
information on thread stack, which is obtained by get_thread_info().

_get_thread_info() stub is added (actually, readded) which always returns
B_ERROR. Moreover, the check in BReferenceable destructor is modified
so that it does not fail when get_thread_info() fails.
