fix inadvertent use of uninitialized variable in dladdr

Browse Source 
commit c8b49b2fbc introduced code that
checked bestsym to determine whether a matching symbol was found, but
bestsym is uninitialized if not. instead use best, consistent with use
in the rest of the function.

simplified from bug report and patch by Cheng Liu.
