[Tarantool-patches] [PATCH v1 luajit 16/41] perf: adjust meteor in LuaJIT-benches

[Sergey Kaplun]

This patch adjusts the aforementioned test to use the benchmark
framework introduced before. The arguments to the script still can be
provided in the command line run. However, the values greater than the
maximum possible solutions found do not affect the time of execution for
this benchmark. Hence, the number of items to proceed is considered
constant as the maximum possible number of solutions.
