[PATCH] commands: i2c: Listen for CTRL-C when probing

[Andrey Smirnov <andrew.smirnov@xxxxxxxxx>]

Allow I2C bus probing to be interrupted early by sending CTRL-C. This is
usefull when calling the tool without any arguments and one of the busses
is misconfigured (waiting for 100+ failures is pretty inconvenient).
