Update stateful size calculation in mod_image_for_recovery

The default size calculated for stateful in mod_image_for_recovery.sh
wasn't leaving enough space for logs.  Adjust the calculation to be
more generous.

This also changes the meaning of the --statefulfs_sectors option
to be more useful by providing a minimum numbmer of free sectors,
rather than a minimum total sectors.

BUG=chromium:469195
TEST=Mount stateful from a recovery image, check free space
