Fix xo_emit format string for percentages
When (long) and (long long) are different sizes vmstat reports garbage for the
CPU percentage columns. From arm.armv7 running FreeBSD 14:
# vmstat
procs memory page disks faults cpu
r b w avm fre flt re pi po fr sr mmc0 da0 in sy cs us sy id
4 0 0 494M 1.2G 278 0 1 0 351 22 0 0 1.7k 603 279 3499288
538751558161 538751558161
The call to xo_emit in usr.bin/vmstat/vmstat.c function percent() passes "
{:user/%2lld/%lld}" as the format string but (long) as the argument type.
Changing "lld" to "ld" fixes the bug.
