Subject[PATCH AUTOSEL 5.4 079/187] kselftest: Support old perl versions
Date
From: SeongJae Park <sjpark@amazon.de>

[ 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.
