xlat: override the value of AUDIT_FEATURE_CHANGE constant

Linux kernel commit v3.15-rc1~18^2~1 has changed the value
of AUDIT_FEATURE_CHANGE constant introduced by commit v3.13-rc1~19^2~20
which is of course an ABI breakage that affected 3.13 and 3.14 kernel
releases as well as their LTS derivatives.

Linux kernel commit v3.15-rc1~18^2~1 also claims that the old value
of AUDIT_FEATURE_CHANGE was ignored by userspace because of the
established convention how netlink messages for the audit system
are divided into blocks.

Looks like the best way to handle this situation is to pretend that
the old value of AUDIT_FEATURE_CHANGE didn't exist.

* xlat/nl_audit_types.in (AUDIT_FEATURE_CHANGE): Undefine.
