[OE-core] Add archiver folder to SSTATE_DUPWHITELIST

[Adrian Freihofer]

Bitbake fails with an error message such as "The recipe bla is trying to install files into a shared area when those files already exist."
Conditions:
 - The archiver class is active
 - Bitbake is called more than once e.g. to compile two images for different architectures

At least for me, the patch bellow seems to solve the issue...

Subject: [PATCH] Add archiver folder to SSTATE_DUPWHITELIST

Without this patch the source archiver class is not allowed to
archive the same source archive for different builds.
