Why gzip is not included in tcpdump ?

Because it just relies on libpcap to write capture files.

or in libpcap directly ? (via zlib)

That could probably be done, given that libpcap files are written purely
sequentially.  Having libpcap *require* zlib would probably not be a
good idea (Ethereal, for example, supports reading gzipped files if you
have zlib, but if you have a system without zlib, Ethereal can still be
compiled, it just can't read gzipped files).
