Provide a default sandboxuser

Browse source 
If sandboxuser is not set, pacman/libalpm does not handle moving
incomplete download files out of the temporary download directories
and into the cache. This leave download_XXXXXX directories in the
cache that cause warnings on -Sc operations.

Initialise the sandboxuser with the username of UID 0 (root on most
systems).

Fixes #209.
