vboot2: Reduce minimum required work buffer size

Apparently our initial submission of 16K was a little too generous for
    the vboot2 work buffer, and I hear that we should also be well within
    bounds for 12K. This patch reduces the minimum asserted by memlayout so
    some of our low-mem boards can get a few more kilobytes back for
    discretionary spending. Also changes the required minimum alignment to 8
    since that's what the current vboot code aligns it to anyway, and add a
    warning comment to make it clearer that this is a dangerous number
    people should not be playing with lightly.

BRANCH=None
    BUG=None
    TEST=Built and booted on Pinky.
