The kflag is supported now for BTF_KIND_ENUM.
So remove the test which tests verifier failure
due to existence of kflag.
With enum64 support in kernel and libbpf,
selftest btf_dump/btf_dump failed with
no-enum64 support llvm for the following
enum definition:
enum e2 {
C = 100,
D = 4294967295,
E = 0,
};
With the no-enum64 support llvm, the signedness is
'signed' by default, and D (4294967295 = 0xffffffff)
will print as -1. With enum64 support llvm, the signedness
is 'unsigned' and the value of D will print as 4294967295.
To support both old and new compilers, this patch
changed the value to 268435455 = 0xfffffff which works
with both enum64 or non-enum64 support llvm.
