bitbake: fetch2: Handle multiconfig fetcher issues

We need a separate fetcher cache per multiconfig as the revisions and other
SRC_URI data can potentially be different. For now, this is the simplest way
to achieve that and avoids linux-yocto kernel build failures when targeting
multiple machines for example.
