xlat: handle xlat constants that are not identifiers

Extend xlat generator to support such input lines as
	IPV4_DEVCONF_FORWARDING-1	0

This is going to be used later in IFLA_AF_SPEC decoding.

* xlat/gen.sh (cond_def): If the xlat value is not an identifier name,
extract an identifier name from the beginning of xlat value.
