[PATCH 3/3] fetch2/npm: ignore unknown headers in tarballs

[Paul Eggleton <paul.eggleton@linux.intel.com>]

Tarballs that are fetched down via npm repositories seem to often have
unknown headers. This doesn't affect our ability to extract the contents
though so we don't really care to see those warnings.
