[PATCH 3/3] virbitmaptest: Add test for out of bounds condition

[Peter Krempa <pkrempa@xxxxxxxxxx>]

Previous patch fixed an issue where when parsing a bitmap from the a
string the bounds of the bitmap weren't checked. That flaw resulted into
crashes. This test tests that case to avoid it in the future.
