Removed .sh suffix in download wrapper script
We don't have a `.sh' suffix in the other scripts of `reproduce/src/bash', so it was also removed from this script.

-# $ ./download-multi-try downloader lockfile input-url downloaded-name
-#
-# Due to temporary network problems, a download may fail suddenly, but
-# succeed in a second try a few seconds later. Without this script that
-# temporary glitch in the network will permanently crash the pipeline and
-# it can't continue. The job of this script is to be patient and try the
-# download multiple times before crashing the whole pipeline.
-#
-# LOCK FILE: Since there is ultimately only one network port to the outside
-# world, downloading is done much faster in serial, not in parallel. But
-# the pipeline's processing may be done in parallel (with multiple threads
-# needing to download different files at the same time). Therefore, this
-# script uses the `flock' program to only do one download at a time. To
-# benefit from it, any call to this script must be given the same lock
-# file.
