[PATCH v4 2/2] testpmd: enable interrupt in interactive mode

[Stephen Hemminger <stephen@networkplumber.org>]

The setting in terminal handling for both Unix style and
Windows was not ensuring that Ctrl-C character would
cause interrupt.

This is a first release bug. Testpmd interactive mode has
always disabled control-c handling on Linux.

Fixes: af75078fece3 ("first public release")
