Avoid disk cache on MacOS by default since it breaks debugging (#7702)

Browse Source 
There's no way for the user to override and disable the disk cache once
a path is specified in our current version of bazel. Later versions
would allow the user to specify `--nodisk-cache`. If the user really
wants a disk cache anyway, they can specify as such in their
`user.bazelrc` file.
