[Tarantool-patches] [PATCH 1/2] cmake: move jepsen targets under option WITH_JEPSEN

[sergeyb at tarantool.org]

From: Sergey Bronnikov <sergeyb at tarantool.org>

For running Jepsen tests we need to checkout external repository with tests
source code on a build stage. This behaviour brokes a Tarantool build under
Gentoo. Option WITH_JEPSEN enables targets only when they needed.

Closes #5325
