MINOR: tools: also protect the library name resolution against concurrent accesses

This is an extension of eb41d768f ("MINOR: tools: use only opportunistic
symbols resolution"). It also makes sure we're not calling dladddr() in
parallel to dladdr_and_size(), as a preventive measure against some
potential deadlocks in the inner layers of the libc.

(cherry picked from commit 8d0c6336778fed316a174fd278c78a88f7dd6975)
