Avoid plotting data of different length in rtp log plotting tool.

During a fix of an unrelated issue, a bug was introduced in the rtp analyzer tool: when the number of data points was divisible by RTPStatitstics.PLOT_RESOLUTION_MS (which is 50), pyplot.plot was called with arrays of different lengths. One of the arrays could be one element larger.

This change trims the potentially longer array to the size of the smaller one.
