spoofer: remove host build + cleanups

The host build is not used by anything.

Added PKG_INSTALL for consistency between packages.

Added PKG_BUILD_PARALLEL for faster compilation.

Added missing protobuf/host build dependency. This was previously
specified as a host dependency, which is wrong.

Removed pointless std parameter.  It's only useful for old G++ versions.
