trx_toolkit/trx_sniff.py: print exact message parsing error

For sure, the following message is much more informative:

  Ignoring an incorrect message: Unhandled version 12

than:

  Failed to parse message, dropping...

NOTE: since the way of printing exceptions is different in both
Python versions, I had to drop Python 2 support.
