btf: Protect BTF_KIND_INFO against invalid kind

If the user provides a kind value that is more than 5 bits, the
BTF_KIND_INFO macro would emit incorrect values for info (by clobbering
values of the kind flag).

Tested on x86_64-redhat-linux.

include/ChangeLog:

* btf.h (BTF_TYPE_INFO): Protect against user providing invalid
kind.
