[kbd] [PATCH] src/libkeymap: better error message on unsupported unicode value

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 symbol can be parsed, and later generate a
better error message:
	unicode keysym out of range: U+1f12f

At least users will know what is wrong with their keymap.
