[OE-core] [PATCH] sstate: Add rpm allarch to overwrite whitelist

[Richard Purdie]

The packagegroup allarch rpm files for multilib can overwrite each other since
they are in theory indentical (in contrast to the other backends). We therefore
need to whitelist this to avoid build failures now this overwrite failure
is fatal.
