[PATCH v3 5/5] selftests/landlock: Fix format warning for __u64 in net_test

["Mickaël Salaün" <mic@digikod.net>]

On architectures where __u64 is unsigned long (e.g. powerpc64), using
%llx to format a __u64 triggers a -Wformat warning because %llx expects
unsigned long long.  Cast the argument to unsigned long long.
