Commit 8da2a8838365 ("rv: Add KUnit tests for some DA/HA monitors")
introduced a division of a 64-bit value by 1000 in the nomiss KUnit
test. This does not compile on 32-bit systems, as standard division of
64-bit values leads to an undefined reference to __udivdi3.
Fix the build on 32-bit systems by using div_u64().
