vt: defkeymap: Map keycodes above 127 to K_HOLE

commit b43cb4ff85da5cf29c4cd351ef1d7dd8210780f7 upstream.

The maximum number of keycodes got bumped to 256 a very long time ago,
but the default keymaps were never adjusted to match. This is causing
the kernel to interpret keycodes above 127 as U+0000 if the shipped
generated keymap is used.

Fix this by mapping all keycodes above 127 to K_HOLE so the kernel
ignores them.

The contents of this patche were generated by rerunning `loadkeys
--mktable --unicode` and only including the changes to map keycodes
above 127 to K_HOLE.
