utils/ssh, host: Remove sudo prompt from output

Browse Source 
On a target where sudo is required, target.file_exists() erroneously
returns True despite the execute() output being:

  '[sudo] password for valsch01: 0\n'

The sudo prompt is being written to stderr (as per sudo -S), but this is
still merged into the final execute() output. Get rid of the prompt to
prevent it from interfering with any command output processor.
