This change fixes calculation of width in case user pipes the output.
SS output output works correctly when stdout is a terminal. When one
pipes the output, it tries to use 80 or 160 columns. That adds a
line-break if user has terminal width of 100 chars and output is of
the similar width. No width is assumed here.
To reproduce the issue, call
ss | less
and see every other line empty if your screen is between 80 and 160
columns wide.
This second version of the patch fixes screen_width being set to arbitrary
value.
