jlink: Adjust log verbosity of libjaylink 

Currently, the log verbosity of libjaylink is not accessible from the
user interface. Therefore, changing the log verbosity of libjaylink is
only possible from within the J-Link driver source code which is not
acceptable for end users.

Output the libjaylink log messages through the logging module of
OpenOCD rather than directly to stderr.
