Thank you for reworking this! Daniel already told me that a fallback is
required if SOURCE_DATE_EPOCH is unset, this looks like a clean solution.

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.
