Fix get-daml.sh installation script (#12487)
* Fix get-daml.sh installation script.

Summary of changes:

* don't fail if TEMPDIR isn't set
* don't change directories at all, so TEMPDIR works with relative file
* don't use df and awk unless we know those commands exist (it feels weird
  to use those without checking, when we check if curl and tar exist)
* remove the daml cache on a fresh install
