[Tarantool-patches] [PATCH 2/4] test: adjust luajit-tap testing machinery

[Igor Munkin <imun@tarantool.org>]

This changeset makes possible to run luajit-tap tests requiring
libraries implemented in C:
* symlink to luajit test is created on configuration phase instead of
  build one.
* introduced a CMake function for building shared libraries required for
  luajit tests.
