packaging: provide RINGTONE_DIR in install.sh

OSX client uses ring-project for its packaging.
when running make-ring --install daemon and client install prefixes are
different. This means ringtones are not packaged properly (they are in
daemon folder /share/ring/ringtones).

This variable can help all clients to point out to a specific external
dir containing ringtones. It will be ignored if not used.
