Alexey Dobriyan 62cb517bb8 proc: fixup uptime selftest
[ Upstream commit 5cc81d5c81af0dee54da9a67a3ebe4be076a13db ]

syscall(3) returns -1 and sets errno on error, unlike "syscall"
instruction.

Systems which have <= 32/64 CPUs are unaffected. Test won't bounce
to all CPUs before completing if there are more of them.
