[Tarantool-patches] [PATCH v2] static build: add openssl build as part of cmake

[HustonMmmavr]

From: Yaroslav Dynnikov <yaroslav.dynnikov@gmail.com>

* Moved openssl build from Dockerfile.staticbuild to CMakeLists.txt
  as `ExternalProject_Add()`

* Prevent build shared libcurl libraries if cmake option
  -DBUILD_STATIC=ON is set

Closes #5043
