libdl: first execute all destructors, then munmap library
Fix problem which might exist since 2011. We need to execute
the destructors for all dependant libraries, before munmap the
shared libraries, otherwise running destructor of a dependent library
might cause a segfault, trying to access an already unmapped memory.
This fixes for example segfaults while running php -m with ldap
module.
