[PATCH trivial] plugins: add missing callbacks to version history

The discontinuity and system call filter callbacks were not reflected in
the versioning comments before. The callbacks have been introduced in
aac73d85d2d6f556dbcee6041a2898cb0ef9b0e6 and
5ed628d1d398b164053f5d5685541ea705275998, respectively.
