populate_fs do copy the xattrs for all files and directories, but the
root directory is skipped and as a result its extended attributes aren't
set. This is an issue when using mkfs to build a full system image that
can be used with SElinux in enforcing mode without making any runtime
fix at first boot.
This patch adds logic to set the root directory's extended attributes.

Since v1:
- Moved the set_inode_xattr logic for the root directory
from __populate_fs to populate_fs2.
