    test: support tarantool cli in lua-Harness
 
    The patch[1] from lua-Harness suite adjusts some checks in
    lua-Harness tests, so they are compatible with Tarantool now.
 
    As a result, the introduced assertion for Tarantool error message fails
    on MacOS, since getopt_long(3) yields the error message without single
    quotes wrapping the flag. Hence, this commit also includes fix for that
    from patch[2] in the trunk.
