sstatesig: Test cross/native hashserv method extension

We can have one taskhash which represents multiple native/cross sstate objects
since they're stored by BUILD_ARCH or possibly host distro (or host gcc version).
We need to put these into separate namespaces on hashserv since their outhashes
will never match and we need deterministic lookups for the different namespaces.

Use this extramethod option to handle this. This fixes several problematic
failures on the autobuilder.
