[3/4] kernel-shark: Set text color to black in KsTraceGraph's axes labels

Commit Message

At present, background color of axes labels of the plot is forced to
white with a stylesheet, but the text color stays unchanged. As a
result, text is barely visible when using dark color schemes. This
patch forces the text color to black for these labels, making them
readable on all color schemes.
