[ Upstream commit 4eac734486fd431e0756cc5e929f140911a36a53 ]
On an old perl such as v5.10.1, `kselftest/prefix.pl` gives below error message:
Can't locate object method "autoflush" via package "IO::Handle" at kselftest/prefix.pl line 10.
This commit fixes the error by explicitly specifying the use of the `IO::Handle` package.
