Today, find_proxy_manager() tests if AddRef() returns 0 in an attempt to
protect against a race condition bug.

Note that AddRef does not return zero in normal circumstances, since
AddRef returns the reference count after the increment, not before.

Fix this by comparing the return value of AddRef() against 1, not 0.

This is likely a regression from cd4f48f2.

Fixes regression caused by aa3699dd.

Doing it this way avoids passing Unix library pointers throught PE.
