[Tarantool-patches] [PATCH v2 luajit 03/30] test: adapt Lua 5.1 suite for out-of-source build

[Sergey Kaplun]

When tests are run out-of-source redefined `dofile()` function
failed to find file to load. So, fullpath is detected considering
`arg[0]` value. Moreover, some tests use `loadfile()` instead, so
their argument is adjusted to the full path to the files.

However, test in <verybig.lua> creates a temporary file
and executes it via `dofile()` too, so this case is handled by
the second argument -- `prefix` equals an empty string for
current working directory.
