sched/accounting, proc: Fix /proc/stat interrupts sum

Commit 3292beb3 ("sched/accounting: Change cpustat fields to an array")
deleted the code which provides us with the sum of all interrupts in the
system, causing vmstat to report zero interrupts occuring in the system.

Fix this by restoring the code.
