It looks like for the purpose of the example "a" logger was needed, so not strictly logrus (probably `fmt.Println()` would've worked even). This patch removes logrus as dependency for the example. The only remaining use of logrus in this repository is now in the pkg/etc/etwlogrus package, which _does_ need logrus, but (possibly) could become its own module if we want to remove logrus as dependency of go-winio itself.
