sstate.bbclass: normalize whitelisted paths

Without this a whitelisted path containing /../ breaks the test for a file
allowed to be provided by more than one recipe.

Noticed when local.conf contains:
DEPLOY_DIR = "${TOPDIR}/../deploy"

|ERROR: core-image-minimal-1.0-r0 do_image_complete: The recipe
| core-image-minimal is trying to install files into a shared area when those
| files already exist. Those files and their manifest location are:
| .../poky/deploy/images/qemux86/README_-_DO_NOT_DELETE_FILES_IN_THIS_DIRECTORY.txt
| Matched in b'manifest-qemux86-linux-yocto.deploy'
