[PATCH] tests: write all pairs of partition table types

[Jim Meyering]

I wrote this a long time ago, back when I noticed
that writing some time of partition table would segfault
but only if the table being overwritten was of some other type.
Since then, I've changed how "clobbering" works, so there is
far less risk of such a problem, but I'm adding the test regardless.
