BUILD: tools: avoid a build warning on gcc-4.8 in resolve_sym_name()

A build warning is emitted with gcc-4.8 in tools.c since commit
e920d73f59 ("MINOR: tools: improve symbol resolution without dl_addr")
because the compiler doesn't see that <size> is necessarily initialized.
Let's just preset it.
