improve turborepo caching (#64493)

### What?

There is a race condition in the `pull-build-cache` script. When the
remote cache entry was removed between the dry run and the real run, it
will run the command and caches whatever is in the native folder.

Seems like there are some very old leftover files there which lead to an
broken publish.

This changes the command to fail when there are no files and empties the
folder before running the script. This should lead to pull-build-cache
to failing instead.

Closes PACK-2957
Fixes #64468
