[Tarantool-patches] [PATCH 4/5][v3] ci: enable checkpatch

[Sergey Bronnikov]

From: Sergey Bronnikov <sergeyb at tarantool.org>

Patch adds a GitHub Action, that clones checkpatch repository, and adds
a job, that runs checkpatch [1] using CMake target "LuaJIT-checkpatch"
against commits on top of the master branch.
