package/hiredis: enable host package

The host-hiredis package is needed for the upcoming ccache update.
So, being a dependency of ccache, we can't use ccache, so we must unset
the options set by the cmake infra (this will be true only when we
eventually bump ccache, but hiredis builds very fast even without ccache
so we don't care about ccache even now).

Reorder CONF_OPTS assignments so that comments apply equally to the host
and target variants.

[yann.morin.1998@free.fr:
  - add Dominik and Anders in Cc to ack they provided inspiration
  - use -Ufoo instead of -Dfoo=""  (as per Dominik & Anders)
  - reorder CONF_OPTS assignments
