Enable qemu autopkgtests for ktls-utils

[Salvatore Bonaccorso <carnil@debian.org>]

Hi

For ktls-utils in the Debian kernel team we have the autopkgtests with 

Restrictions: isolation-machine, needs-root, breaks-testbed, skippable

It is not possible to run the autopkgtests under LXC, as we exercise
the NFS functionality and running under LXC has some problems:
https://salsa.debian.org/kernel-team/ktls-utils/-/commit/060f3416db74fe70bd0c65cecacafe58969dfcb0

Can you enable ktls-utils to have its autopkgtests running?

Regards,
Salvatore
