Prevent file injection writing to host filesystem.
Fix bug 1015531, CVE-2012-3360, CVE-2012-3361
This patch prevents the file injection code from writing into the host
filesystem if a user specifies a path for the injected file that
contains '..'. The check is to make sure that the final normalized path
that is about to be written to is within the mounted guest filesystem.
