I have updates for genext2fs and genimage!

Newer versions of the genext2fs tool have support for things like
SOURCE_DATE_EPOCH, and Guix seems keen on reproducible builds, so Guix
may as well have the latest and greatest genext2fs!

Updating genext2fs triggered test suite failures in genimage, which I
also noticed was a slightly out of date... so updated that too!

Will submit the patches once I get a bug number... (that's really how
this is supposed to be done still?)


live well,
