[vlfeat] fix incorrect header install path, expose OpenMP as a feature (#39379)
Fixes the headers being installed under `vlfeat/` instead of `vl/` by
the custom CMakeLists.txt.

The project docs use `#include <vl/...>`
(https://www.vlfeat.org/api/kmeans.html) and so does the Debian package
(https://packages.debian.org/sid/amd64/libvlfeat-dev/filelist), for
example.

I also included a patch from Debian to fix OpenMP support and exposed
OpenMP as an optional feature.

Related to #39354.
