build: image: add common and reproducible IMG_PART_SIGNATURE variable
x86, mvebu and tegra targets are currently using more or less same
SIGNATURE variable which provides unique partition ID/signature, so it
makes sense to refactor it out into common variable which could be
reused by all targets. While at it, make the content of the variable
reproducible.
