Increase witherspoon host console log to 256K

The host team has requested a bump in their allocated log
size. Appears as if witherspoon has the filesystem space
to spare so bump up from the default of 16K to 256K.

Testing: Loaded on system and caused a lot of traffic in
host console and verified /var/log/obmc-console.log did
not grow beyond 256K and properly wrapped.
