Dongsu Park 8243944c99 sys-kernel: enable metacopy and redirect_dir for overlayfs ...

Enable CONFIG_OVERLAY_FS_METACOPY, metadata only copy up feature
in overlayfs. When turned on, overlayfs will only copy up metadata
when a metadata specific operation like chown/chmod is performed.
Full file will be copied up later when file is opened for WRITE
operation. More or less like delayed data copy up operation.

Enable CONFIG_OVERLAY_FS_REDIRECT_DIR, which is equivalent to
"redirect_dir=on" in the kernel command-line. When turned on, overlayfs
will copy up directory first, before the actual contents.
