package/hwloc: bump to version 2.4.1

- Add ac_cv_prog_cc_c99 to avoid a build failure due to
  https://github.com/open-mpi/hwloc/commit/f2226f76e104923a76c5d09328284104abad6b01
- Update hash of COPYING, copyrights added with
  https://github.com/open-mpi/hwloc/commit/ebaa3595e2ddc6e0e94e8ea5b1472f1a21969c80
- Update indentation in hash file (two spaces)

As a side effect, this will remove numactl dependency (which raises a
build failure with sparc v8 since commit
4ed540ddf59bec4b389be44d7f42820d2466904f) thanks to:
