nixos/shells: support defining aliases beginning with a dash or plus 

Both Zsh and Bash support aliases that begin with characters also used to
indicate options to the “alias” built-in command, as long as the alias
definition is preceeded by a double dash.

This allows, e.g, for “alias -- +x=chmod +x”.
