Continuous Fuzzing Integration with Fuzzit

includes two travis ci steps:

1) Every pull-request/push all fuzzing targets will do a quick
sanity run on the generated corpus and crashes (via Fuzzit)
2) On a daily basis the fuzzing targets will be compiled (from
master) and will and their respectible fuzzing job on Fuzzit
will be updated to the new binary.

+When you add a new target you should also add the target on [Fuzzit](https://app.fuzzit.dev/admin/RxqRpGNXquIvqrmp4iJS/dashboard)

+ `travis-ci/managers/fuzzit.sh` so the new target will run sanity tests on every pull-request and periodic fuzzing jobs.

 If you find a bug that impacts the security of systemd, please follow the
 guidance in [CONTRIBUTING.md](CONTRIBUTING.md) on how to report a security vulnerability.
