[Packaging][OSX] Nightly builds on MacOS are failing because of brew compile timeouts

[asfimport]

Home-brew in our packaging builds has recently started to compile the dependencies instead of installing precompiled binaries. I'm not sure what's the issue, perhaps it is because the too old Xcode.

But the error for the homebrew-cpp job was actually

Prudhvi Porandla / @pprudhvi:
@nealrichardson, I desperately needed the build to pass so I started working on it. I changed image version to xcode9.4, removed cmake upgrade, and turned off arrow-dataset, arrow-filesystem. With these change the build takes about 40min which is ~10min more than what it used to be. This is the PR #5681
