Update initrd.gz/lib/keymaps/*

Keymap files rebuilt using loadkeys' "--unicode" option.
All except se.gz (couldn't find that one).

So far haven't noticed any negative side effects in comparison to the behaviour of original keymaps.
The only difference is that typed diacritics are properly displayed now.

Not sure if there's need to include the rebuilt files for keymaps like 'us' or 'dvorak', but they seem to behave the same way like the originals, so...

Sadly, no feedback here:

nor there:

but I'd say let's do it anyway - if it breaks anything, surely _then_ we'll get the feedback. ;)
Besides, there will be at least one more beta before the final, right?
