conntrackd: add `-s queue' to display queue statistics

This patch re-introduces `-s queue' but now it displays generic
queue statistics.

# conntrackd -s queue
active queue objects:                      0

queue txqueue:
current elements:                          0
maximum elements:                 2147483647
not enough space errors:                   0

queue rsqueue:
current elements:                         72
maximum elements:                        128
not enough space errors:                   0
