sockstat: improve handling of path state

Only suppress the path state column when producing traditional text
output. When generating html output, always include the column.
Please note that when generating json or xml output, optional fields
like the path state are only generated if they is applicable. This
has not been changed.
The changes in this patch were suggested by asomers.
