Commit 0ab8ed18a6fe98bfc82705b0f041fbf2a8ca5b60 ("trace: switch to
modular code generation for sub-directories") forgot to convert "tcg"
trace events to the modular code generation approach where each
sub-directory has its own trace-events file.
This patch fixes compilation for "tcg" trace events. Currently they are
only used in the root ./trace-events file.
"tcg" trace events can only be used in the root ./trace-events file for
the time being.
