Remove showing the "allow" button for "allow one time" on automotive

There appears to be cases where permission dialogs show
"Allow one time", "Allow while in foreground", and "deny".
The current code, since we don't want to show one time
permissions on automotive, would change that to
"Allow", "Allow while in foreground", and "deny",
where "Allow" and "Allow while in foreground" do the
same thing. It should really just have "Allow while in
foreground" and "deny".
