ExternalProject: Fix download retry logic 

Do not check file's hash in download script.  If hash will not match
command ``file(DOWNLOAD ...)`` will fail with FATAL_ERROR, ``cmake -P``
will exit with unsuccessful code, and the build will stop.  Leave hash
checking to the existing implementation in the verify step.
