Telegram: improve identification
Follow up of 31c706c3dbbf0afc4c8e0a6d0bb6f20796296549 and
75485e177ccc4fafcc62dd46c6917d5b735cf7d2.
Allow fast classification by ip, but give time to other dissectors to
kick in (for example, the TLS code for the Telegram Web flows).
Even if we don't classify it anymore at the very first packet (i.e. SYN)
we fully classify Telegram traffic at the first packet with payload, as
*any* other protocol.
This way, we always have the proper category, the proper confidence
for the UDP flows and we don't overwrite previous classifications (TLS
or ICMP)
Remove old and stale identification logic for TCP flows
