package/opencv4: do not detect ccache

OpenCV-4'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.

Commit 505e7f47715c77d8586444a4fefe4a190b77aaad already applied this
change to opencv3.
