Fix newsyslog(8) to use the size of the file instead of the blocks it
takes on disk, as advertised in newsyslog.conf(5).
This fixes newsyslog(8) on ZFS with compression enabled to not have
large files compared to the expected rotation size.
# grep remotes/messages /etc/newsyslog.conf
/var/log/remote/messages root:info 640 5 500 * JC
# ls -alh /var/log/remote/messages
-rw-r----- 1 root info 3.2M Jan 31 20:02 /var/log/remote/messages
# newsyslog -vN|grep remote/messages
/var/log/remote/messages <5J>: size (Kb): 464 [500] --> skipping
# stat -f "st_size: %z st_blocks: %b" /var/log/remote/messages
st_size: 3372627 st_blocks: 928
# zfs get -H compressratio zroot/syslogs
zroot/syslogs compressratio 3.77x -
With fix:
# newsyslog -v | grep remote/messages
/var/log/remote/messages <5J>: size (Kb): 3338 [500] --> trimming log....
