contrib: remove the CMakeCache.txt at every run

Just like we do with autotools builds, we configure the target every time we
build a contrib.

In the case of cmake, touching `toolchain.cmake` does rebuild the cmake
contribs but if there's a cache it's not reconfigured and doesn't rebuild
anything.
