ExternalProject: Restore logic to not download already-existing file
The change in commit v3.1.0-rc1~85^2 (ExternalProject: Fix download retry logic, 2014-09-13) dropped the file(DOWNLOAD) EXPECTED_HASH argument. This prevents file(DOWNLOAD) from skipping the download if the output file already exists with the proper hash. Restore this check with explicit code in the download script.
