tests: Fix guest building so parallel 'make -jN check' works.

This means renaming various temporary files (eg. fstab.tmp) that
several of the scripts were using so they don't conflict
(eg. fstab.tmp.$$).

Also the rule:

  fedora-md1.img fedora-md2.img: guest-aux/make-fedora-img.pl

causes the script to run twice in parallel when using 'make -jN'.
Replace this with a stamp file so it runs once:

  fedora-md1.img fedora-md2.img: stamp-fedora-md.img
  stamp-fedora-md.img: guest-aux/make-fedora-img.pl
