sstate.bbclass: make hard links for staging files
Make hard links for staging files instead of copy to save the disk space
(3G will be saved for a core-image-sato build), and it doesn't affect
much on the build time.
The following directories are affected:
1) The sysroot
2) The DEPLOY_DIR
3) The pkgdata
