Fix hash/encrypt library searching (#5804)

* Corrected maxos niantic lib filename

Filename is libniantichash-macos-64.dylib not libniantichash-osx-64.so

* Better search for encrypt/hash files

Instead of just looking in root, or encrypt_location, or whatever the
heck the last person did... will first search local or encrypt_location.
If not found, will search pgoapi/lib. If still not found, abort.
