Make install-from-binstall-release work with POSIX sh (#1984)

This script would be useful to run in Docker containers, which don't
always have `bash` available (e.g. Alpine). It just needs a few small
adjustments to make this work, so apply those changes here.

Tested this script in an Alpine container.
