[Buildroot] [PATCH v8 14/16] squashfs: Add xattr support

[Clayton Shotwell]

Adding extended attribute support for the squashfs tools when the attr
package is selected. This is needed for SELinux support.

Signed-off-by: Clayton Shotwell <clayton.shotwell at rockwellcollins.com>

---
Changes v7 -> v8:
  - Reverted changes to the host build options to leave xattr support
    disabled due to too many host system dependencies issues.
  - Cleaned up the target xattr options and added a dependency on attr
    to ensure it is built before squashfs (Suggested by Thomas P.)

Changes v6 -> v7:
  - No changes

Changes v5 -> v6:
  - No changes
