io_uring/sqpoll: switch away from getrusage() for CPU accounting
Commit 8ac9b0d33e5c0a995338ee5f25fe1b6ff7d97f65 upstream.
getrusage() does a lot more than what the SQPOLL accounting needs, the
latter only cares about (and uses) the stime. Rather than do a full
RUSAGE_SELF summation, just query the used stime instead.
