libjaylink: Update for API changes

Update to latest libjaylink version and incorporate API changes.

The major change in libjaylink is a rework of the device discovery.
Please test device discovery extensively, especially with multiple
devices connected. All other changes in libjaylink are of minor
importance for OpenOCD.
