Prohibit file injection writing to host filesystem
This is a refinement of the previous fix in commit 2427d4a9,
which does the file name canonicalization as the root user.
This is required so that guest images could not for example,
protect malicious symlinks in a directory only readable by root.
Fixes bug: 1031311, CVE-2012-3447
