Hello, thank you for the review!

Here are required fixes:

1. Fixed typos at commit message, here is a new:

build: refactor static build process

Refactored static build process to use static-build/CMakeLists.txt
instead of Dockerfile.staticbuild (this allows to support static
build on macOS). Following third-party dependencies for static build
are installed via cmake `ExternalProject_Add`:
    - OpenSSL
    - Zlib
    - Ncurses
    - Readline
    - Unwind
    - ICU

* Added support static build for macOS
* Fixed `CONFIGURE_COMMAND` while building bundled libcurl for static
    build at file cmake/BuildLibCURL.cmake:
    - disable building shared libcurl libraries (by setting
        `--disable-shared` option)
    - disable hiding libcurl symbols (by setting
        `--disable-symbol-hiding` option)
    - prevent linking libcurl with system libz (by setting
        `--with-zlib=${FOUND_ZLIB_ROOT_DIR}` option)
* Removed Dockerfile.staticbuild
* Added new gitlab.ci jobs to test new style static build:
    - static_build_cmake_linux
    - static_build_cmake_osx_15
* Removed static_docker_build gitlab.ci job

Closes #5095

2. Fixed commentaries at .travis.mk

3. Fixed finding libz library at cmake/BuildLibCurl.cmake as at master
   branch

4. Instead of using static-build/.gitignore use the root .gitignore file

5. Refactored static-build/CMakeLists.txt:
* Project name is set to tarantool-static
* Instead of explicitly finding of c/c++ compilers current version uses
cmake `project(tarantool-static C CXX)` command. This change requires
to manually set CFLAGS/CPPFLAGS/LDFLAGS for all static-build
dependencies (because building dependencies at macOS requires path
to macOS SDK) the idea was taken from cmake/BuildLibCurl.cmake
* Added commentaries about problem with libicu
* Removed unused TEST_COMMAND at ExternalProject_Add(zlib ...) also
removed unnecessary # STEP_TARGETS at ExternalProject_Add(readline ...)
* Deleted doubled whitespaces

6. Fixed static-build/README.md:
* Added list of required tools
* Added example for ubuntu/debian
* Fixed indentation and typos

7. Refactored tests:
* Got rid of test-run
* Deleted whitespaces at exports.test.lua
* Fixed defining of RTLD_DEFAULT
