sstate: Fix SSTATE_DUPWHITELIST variable usage

We need to split this variable before using it. Otherwise a single "/"
character in the list whitelists every overlapping sysroot file which
was not the intention making the whole thing useless.

We'll start seeing warnings about overlapping files now this is working
correctly after this patch.
