[PATCH] tests: Relax unnecessarily-strict constraint Debian's parted package carries a patch to apply alignment constraints to new partitions created on fresh disks. This caused `tests.test__ped_partition.PartitionMSDOSTypeIDTestCase.runTest` to fail as follows:
_ped.PartitionException: Unable to satisfy all constraints on the partition.
While I realize that a Debian patch isn't strictly upstream's problem, in this case the optimal alignment constraint doesn't seem to have anything to do with what's actually being tested, so relax it to a minimal alignment constraint.
