selftests: forwarding: Move DSCP capture to lib.sh

Browse Source 
dscp_capture_install() and dscp_capture_uninstall() are going to be
useful for a test added by a following patch, move them therefore to
lib.sh together with related helpers.

While doing so, change the rule preference from mere DSCP value to
DSCP+100 in order to support adding captures of packets with DSCP of 0.
