Fix decoding error when reading server's log file

When a diff test starts a Tarantool server, test-run reads the server's
log file and tries to find the message indicating the server is ready.
Sometimes the server's log file may contain bytes that cannot be decoded
by `utf-8` codec and test-run fails with an error like this:

    [044] TarantoolInpector.handle() received the following error:
    [044] Traceback (most recent call last):
