uterm: input: add built-in keymap fallback

This adds a small US-keymap to the uterm library which is loaded if we
cannot find a suitable system default keymap. This allows using the keymap
if no XKB keymaps are installed.

Thanks to Ran Benita for the minimal US keymap.

+# XKB Fallback Converter

+# we remove useless lines/characters first.
+# We also append an ASCII 0 character so it can be used as regular C-string.

+# Following regexp are used to remove characters/lines:
