[Tarantool-patches] [PATCH luajit] ci: conditionally install lua-cjson for perf job

We have encountered the flakiness of the network on our CI runners. It
happens only on lua-cjson installation and only in some particular job
run.

This patch helps to deal with it by installing this package only if it
is not installed in the system. Also, it installs it only for Lua 5.1,
which is compatible with LuaJIT.
