Subject: [PATCH] brew.sh: fix some stderr redirections to `/dev/null`

The order matters here (in a way that I can't explain, unfortunately).

Example:

    bash-3.2$ read -r FOO <nonexistent 2>/dev/null
    bash: nonexistent: No such file or directory

    bash-3.2$ read -r FOO 2>/dev/null <nonexistent
    # no output

Fixes Homebrew/discussions#5653.
