[OE-core] [PATCH] wic/imager/direct: Ensure correct ROOTFS_DIR is shown

[Richard Purdie]

This changes the output of "wic create mkefidisk -e core-image-sato" from:

The following build artifacts were used to create the image(s):
  ROOTFS_DIR:                   /media/build1/poky/build/tmp.wic.ybraavmb/rootfs_copy

to:

The following build artifacts were used to create the image(s):
  ROOTFS_DIR:                   /media/build1/poky/build/tmp/work/qemux86_64-poky-linux/core-image-sato/1.0-r0/rootfs

which s much less confusing for the user.
