pw_env_setup: Abort if 'python' is an alias

Detect when 'python' is an alias and cancel bootstrap. Tested on bash,
zsh, and dash.

Also prefer 'python3' when choosing which Python to use for bootstrap.

Finally, fix use of '&>' to redirect both stdout and stderr which
apparently is not POSIX behavior. Instead, use '>' and '2>'.
