Add C-o and C-i keybindings to evil-evilified-state-map (and remove from pdf-view-mode-map)

C-o and C-i are standard vim keybindings to jump back/forward between previous
locations. It is annoying and unnecessary that evilified buffers break that
flow, therefore these keybindings should be added to the
`evil-evilified-state-map` so that they are available automatically in all
evilified keymaps/modes. I assume that by just adding them to the map, all
required remappings will automatically be taken car of by the
`evilified-state-evilify-map` macro (anyway, it seems to work fine).
