Subject: [PATCH] cli: chown before reporting

User must have write access to the reported directory to be able to

report it but abrt-dbus allows the user to read data of problems that

belongs to him which may not be accessible in file system.

The GUI does the same and make sures the user can write to the reported

directory by chowning it before reporting.
