Fix ss command on newer versions of iproute2

Browse Source 
The iproute2 package starting in version 6.7.0 changed the way the ss
command outputs internal TCP information via the -i/--info option which
LookingGlass uses to display latency information.

In prior versions the flags: -Hint would show internal TCP information.
However starting in version 6.7.0 an additional flag -p/--processes
needs to be passed in to get the same information.

The changes were commited upstream in
https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/commit/misc/ss.c?id=87d804ca0854b09c07872e9fd6036bf5d3e0cc85
and effects all versions of iproute2 6.7.0 and later.

Old versions continue to work with and without the -p/--processes flag.
In my limited testing it appears adding extra flag is backwards
compatible and should not break anything.
