Upstream: hide_headers_hash inherited regardless of cache settings.

Dependency on cache settings existed prior to 2728c4e4a9ae (0.8.44)
as Set-Cookie header was automatically hidden from responses when
using cache.  This is no longer the case, and hide_headers_hash can
be safely inherited regardless of cache settings.
