Add a "Control vehicle" menu entry to the examine menu.

I actually wanted to integrate every entry in the vehicle control menu
Inside the examine menu, but that's a lot more of code inside the pickup()
function which should be split in parts.

There are some things that should be cleaned up, the menu should be
in examine() instead of pickup(), for starters.

I kept this simple, it's handy and doesn't change things too much.
Make "let go of controls" the default placing it first in the menu.
Make "stop driving" the second option.
Straight skill parity

Removes the -2 that @swwu mentioned in #5394.  Seems to work more or
less OK: zombie dogs are a serious hazard to a 0-skill character.
