[Tarantool-patches] [PATCH v2 luajit 15/26] test: enable <ffi_lex_number.lua> in LuaJIT-tests

[Sergey Kaplun]

This patch changes the `dofile()` (which uses an unreliable relative
file path and mutates `_G` with global functions to be defined) to the
corresponding `require()`. Also, it adds groups with the names of
subtests and enables the test in <index>.
