[Buildroot] [git commit] package/opencv3: do not detect ccache

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=505e7f47715c77d8586444a4fefe4a190b77aaad
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

OpenCV-3's buildsystem will try to detect ccache and use it if
available. This may yield a system-installed ccache.

However, in Buildroot, ccache is entirely hidden away and handled in the
toolchain wrapper.

Forcibly disable detection of ccache.
