build: SAVE ARTIFACT output location fix (#55)

The destination directory's path if it end with '/' copys to different locations
if the destination exists or not locally, similar to 'cp'.

Setting the destination as './' keeps the behaviour consistent if the
destination exists or not locally and lets us not repeat the name.
