[Tarantool-patches] [PATCH luajit 1/3] test: fix path storage for non-concatable objects

[Sergey Kaplun]

When the key of a table to compare via `tap.test:is_deeply()` is
non-concatable object (i.e. lightuserdata) concatenation with path
raises an error.

This patch converts object to string to avoid this error.

Needed for tarantool/tarantool#5629
