[PATCH] tst: Add test for utime

Hi Lukasz,

It seems that this and the utimes/futimens tests fail on machines where
/tmp is XFS, where they run into a y2038 bug [1].

I am wondering if there's a way around this, like maybe using a loop mount
inside a container? I don't know if that's possible/easy using the
container tests infrastructure, but it is the first thing that comes to my
mind.

Cheers,
Arjun
