[PATCH] sstate: Silence warnings when switching machines

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

We recently added multiple provider warnings. These could get issued 
from -cross recipes due to the way these currently overlap in the 
native sysroot. Filter out these warnings for now, until such times
as we improve the cross recipes so they don't have an overlapping 
namespace.
