[Buildroot] [git commit] package/opencv3: add .hash file

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=76acaafd41135ba8b051548d643d290834cb1383
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Similar to jquery-keyboard, it seems the opencv3 tarball on the
autobuilder is corrupt.  Fix it by adding a .hash file so it falls back to
our s.b.o mirror.
