[OE-core] Question about how to get package included in SDK

[Burton, Ross]

The main problem is that protoc isn't in the protobuf packages, but
protobuf-compiler (as can be seen with oe-pkgdata-util list-pkg-files
-p protobuf).

Add nativesdk-protobuf-compiler to TOOLCHAIN_HOST_TASK.  You'll also
want to use _append instead of += so you don't remove more than you
add.
