vtysh: initialise readline before binding key

when libreadline initialises itself, it also reads .inputrc, which may
result in keybindings being set up.  This means the builtin help on the
'?' key can be overridden by that.  Consistent availability of '?'
behaviour trumps .inputrc setup here, so let's initialise readline
first before binding that key (which means our keybinding wins).
