Hi,
Whilst working on the Reproducible Builds effort [0] we noticed that
petitboot could not be built reproducibly.
This is because it used the build date when working out the package
version.
Patch attached that uses SOURCE_DATE_EPOCH if its available, although
it does prefer the Git checkout if that exists.
