Elm: module unloading

Implements the module unloading to all modules on elm_module_shutdown.
This change also fixes a memory leak within elm_module picked by valgrind.

Here follows the valgrind log:

96 bytes in 1 blocks are definitely lost in loss record 105 of 168
    at 0x4C29DB4: calloc (
            in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
            by 0x52065B6: _elm_module_add (elm_module.c:223)
