common: Increase timeout for socket_send() to reasonable value

The short timeout of 1000 ms might cause problems in different situations
like a firmware restore, where 1000 ms can easily be hit. Increasing this
to a higher value will mitigate it for this case, but actually the error
handling at a higher level needs to be improved.
