Julian Stecklina fd2047c642 nixos/lib/make-ext4-fs: fix after mkfs.ext4 refactoring ...

In 9ac1ab10c9 this library function was
refactored to use mkfs.ext4 instead of cptofs. There are two problems:

If populateImageCommands would create no files (which is fine), a cp
invocation would fail due to missing source arguments.

Another problem is that mkfs.ext4 relies on fakeroot to have sane
uid/gids in the generated filesystem image. This currently doesn't
work for cross compiling.
