tt connect : low print output performance on socket connection

[d-enk]

require("fun").ones():take(50000):totable()

Works very slowly for large objects

Of course, there is no need in itself to print large objects
But sometimes it happens by misclick that causes it to freeze

For comparison native tarantool console work almost instantly

tarantoolctl connect also work good

This is a problem specific for unix socket
By address it works great
