[PATCH] sstate: Relax the duplicate file whitelist for now

[Richard Purdie <richard.purdie@linuxfoundation.org>]

do_package is a machine specific task at the moment due to packagedata. This means
do_package tasks and their dependencies rerun between different machines
with various duplicate file installations. There are plans to fix this but they're
too invasive before release.

This patch relaxes the whitelist for sstate duplicate file detection to account
for this. Post-release, we re-enable stricter settings once do_package is not
machine specific.
