This variable(tflag)looks confusing. Can we use a meaningful name?

I prefer to use dup3(1,4,0) and dup3(1,4,O_CLOEXEC) because it is more
clear.

Lastest upstream kernel has reached to 5.15-rc1 and we don't need to
check this very old kernel version. So we can remove this check.
ps: user who use old distros can use old ltp release to test. I don't
want to keep it.

coe represent what? ret looks better.

I think this case was introduced by long time ago and glibc doesn't
support it so case uses syscall directly. Now, I think using glicb
wrapper is enough.

We don't need to break and should run the second case.
Please use tst_res and return.

Test for various EINVAL error.
EINVAL - oldfd was equal to newfd and doesn't use O_CLOEXEC flag
EINVAL - oldfd was equal to newfd and use O_CLOEXEC flag
EINVAL - flags contain an invalid value.
