trace-cmd: Add a commented single quote to the Makefile

My emacs highlighting gets confused by the single escaped quote, and makes
the rest of the file highlighted as if the rest of the file is part of a
string. By adding a commented out single quote, my emacs editor displays
everything nicely again.
