[Tarantool-patches] [PATCH 2/5] lua/fio: Add lbox_fio_push_error as a separate helper

[Cyrill Gorcunov <gorcunov@gmail.com>]

Since lbox_fio_pushbool always push boolean first
it is inpossible to use it inside other routines.
Thus make a separate helper lbox_fio_push_error
which will be used in popen code later.

Part-of #4031
