[OE-core] [PATCH] oe/image: use apparent size of artifacts, not disk usage

[Ross Burton]

When collecting the size of the root file system get the apparent size of the
files not the actual disk usage, as disk usage on the host file system can be
affected by file system compression or sparse files.
