Fix min swap value in make_swap.sh

Browse Source 
We just discovered that a number of new servers have rather small swap
sizes. It appears this snuck in via change 782898 which tries to bound
the max swap size to 8GB. Unfortunately the input to parted expects MB
so we make a swap size of 8MB instead of 8GB.

Bump the min value to 8192 to fix this.
