Adding hwloc 1.9.0 to third-party directory

[Reviewed (for open source license issues) by Lydia.]

A new hwloc version is available.  Adding the unmodified .tar.gz
and unpacked sources to our third-party directory without making
them the default.

Note that this differs from our addition of the previous 1.7.2 release
in that for the former we didn't add the unpacked sources.  I'm adding
those this time because I expect that we may need to change the sources
in the future.
