[kbd] [PATCH] src/libkeymap: add support for parsing more unicode values

The auto-generated (with ckbcomp) file fr-bepo_afnor did not load (even
partially), because of an U+1f12f (copyleft symbol) that is wrongly
parsed, generating this error message:

	too many (160) entries on one line

Fix libkeymap so that the keymap can be parsed, even if the offending
character won't be loaded because of the ushort limitation of the
kb_value KDSKBENT uapi.

It's better to have the keymap partially loaded than not at all.
