dccp ccid-2: Use u32 timestamps uniformly
Since CCID-2 is de facto a mini implementation of TCP, it makes sense to share
as much code as possible.
Hence this patch aligns CCID-2 timestamping with TCP timestamping.
This also halves the space consumption (on 64-bit systems).
The necessary include file <net/tcp.h> is already included by way of
net/dccp.h. Redundant includes have been removed.
