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

[Sergey Bronnikov via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

From: Sergey Bronnikov <sergeyb@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.
