Subject: [PATCH] TT#83954 Invoke libevent_global_shutdown() only conditionally

Commit a6d2f9296 introduced usage of libevent_global_shutdown(),
which is available in libevent-dev >=2.1.1-alpha only.

For example travis CI is running Ubuntu 16.04 / xenial and ships
libevent-dev 2.0.21-stable-2, so we can't just raise the
build-dependency of libevent-dev to >= 2.1.1+ if we still want
to support older systems.
