libc/elf: Free the registry entry when removing a module.

Browse source 
libelf_remove() takes the module out of the registry but never frees
the registry entry, so every successful rmmod()/dlclose() leaks
sizeof(struct module_s), the name included.  The lib_free() call was
dropped by e9550783d3 when the removal path was reworked.

Free the entry after the registry lock is released.
