west: commands: runners: canopen: increase default SDO timeout

Increase the default SDO timeout for the CANopen program download west
runner from 0.3 seconds to 1 second. Depending on the flash size and speed,
a full erase may take slightly longer than 300 ms.

The timeout can be customized by using the --sdo-timeout runner parameter.
