ipcpd: Add protocol debug option for link-state

The link-state routing component now has a protocol debugging option,
activated by enabling the DEBUG_PROTO_LS flag at build time in a
debug build.

Example output (sender and receiver):

LSU [81:8a:1f:9b -- 50:c6:2d:03 seq: 000000000] --> 50:c6:2d:03
LSU [81:8a:1f:9b -- 50:c6:2d:03 seq: 000000000] <-- 50:c6:2d:03

In larger networks, forwarded LSUs are marked as such:

LSU [ee:53:ae:f8 -- e5:33:e4:8d seq: 000000006] --> e5:33:e4:8d [forwarded]

This also aligns the address printing using a similar ethernet-like
formatting such as the DHT component. Small code cleanup in the graph
component.

Note: eventually the link state dissemination should move to a
broadcast Layer instead of the link state component doing the
forwarding.
