monitor: Add interface for J-Link library

This adds simple interface to libjlinkarm.so which will be used to read
data from RTT buffer. It was mostly made by trial and error since there
is no public documentation for this library so it may lack something,
but seems to work fine with few Cortex-M devices I tried.
