It's currently possible for CIPD bootstraps that provision concurrently to:
1) On Linux, step on each other during download, and
2) On Windows, fail.
Fix these respective scripts so that bootstraps are safe to use
concurrently.
On Linux and Mac, we download to a temporary file and use "mv" (atomic)
to write it to the final destination. Concurrent initializations will
perform parallel downloads, execute the "mv", and copy their downloaded
file to the destination path.
On Windows, we use filesystem locking to lock the operation and ensure
that only one download can happen.

Make Linux/Mac CIPD wrapper fail if any step returns an error.
Include the "-f" curl flag, which will cause it to error on non-200
status.

This takes advantage of powershell on windows for a cleanish duplicate of the
posix version.
