Fix edge cases when specifying the user to run as.

Browse source 
* check the username fits the format expected by adduser;
 * don't allow root;
 * if the user exists, don't try to create it; usually, this is
   harmless, but it fails if the user exists with a UID outside the
   normal range for system users.

Fixes #24.
