Instead of traversing across leafs() which can lead to an infinite loop issue with cross-linked libraries, use the dictionary (libs_dict) created by libraries() to create a set (libs_set) of every unique library. Every value in libs_dict is also a key in libs_dict, so every unique library linked to mpv will be a key in libs_dict. Use set() on libs_dict to return a set of the keys from libs_dict, and remove binary from the set so that a duplicate of the binary is not added to the libs directory. Iterate over libs_set to bundle dylibs while using the libs_dict to determine which install_names to change.
