[Buildroot] [git commit branch/2017.11.x] flann: Disable find package for HDF5

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=fbdcb171be992733fdfc2c4c08ffb4644bc6411c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.11.x

The HDF5 package is used by flann for testing purpose only and is
not part of buildroot packages. However, if present in the host, it will
be used and trigger the unsafe header/library path used in
cross-compilation error.
