disk full test: some improvements

- can create 0-byte files now
- frees space early (avoids running out of disk space at repo init time)
- creates multiple reserve files, so we do not only reserve some space,
  but also some inodes
 - only print output if there is an error RC
 - if make_files makes us run out of space, that is not interesting, just start
   a new iteration from scratch
