contrib/osmo-iuh.spec.in: fix header packaging

Fix the conflict from having %{_includedir}/* in multiple packages by
replacing it with the correct subdir path.

Fix for:
  found conflict of libosmo-hnbap-devel-0.7.0.11.b110.202110260026-1.1.armv7hl with libosmo-ranap-devel-0.7.0.11.b110.202110260026-1.1.armv7hl:
    - /usr/include/osmocom/hnbap/Access-stratum-release-indicator.h
    - /usr/include/osmocom/hnbap/AccessResult.h
    - /usr/include/osmocom/hnbap/AdditionalNeighbourInfoList.h
  ...

I've verified that it builds again in my own OBS namespace.
