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

https://bugzilla.redhat.com/show_bug.cgi?id=997367

Previous patch fixed an issue where, when parsing a bitmap from the
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.

(cherry picked from commit 7efd5fd1b0225436cbbae1181ab41c2d3eca43f9)
