Fix #168: sadf: Fix CSV output for TTY statistics

The TTY number was repeated before each field value in CSV output
display by sadf:

ubuntu;10;2017-09-29 12:00:31 UTC;0;0.00;0;0.00;0;0.00;0;0.00;0;0.00;0;0.00
ubuntu;10;2017-09-29 12:00:31 UTC;1;0.00;1;0.00;1;0.00;1;0.00;1;0.00;1;0.00

Expected output:

ubuntu;10;2017-09-29 12:00:31 UTC;0;0.00;0.00;0.00;0.00;0.00;0.00
ubuntu;10;2017-09-29 12:00:31 UTC;1;0.00;0.00;0.00;0.00;0.00;0.00

This patch fixes the problem.
