Change the nominal swap calculation from 1/2 physical memory to 1/8

physical memory.  The default is still 2x physical memory.  The nominal
calculation is used to back-off swap auto-allocation ('A'uto command)
when the disk is not large enough to accomodate all filesystem auto-defaults.
This gives other partitions (like /usr) more priority over swap on smaller
disks.

This should help solve reported auto-sizing failures on machines with small
hard drives and huge amounts of memory.  For example, a machine with 2G of
disk and 4G of memory will fail to auto-size without this fix.
