Fix fetch-configlet bash script for windows

SleeplessByte · SleeplessByte · commit c4f360d4d5e5 · 2019-04-10T18:02:32.000+02:00
Sync with upstream exercism/configlet#156 * This correctly sets the OS and EXTension when on windows, even when in bash (or a different bourne-shell). * Additionally this uses unzip if the extension is zip, as tar will correctly say the zip is not a tar. `unzip` does not allow for piping, so a temporary file is created.
