insane: remove broken unsafe-references-in-binaries test
This test aims to detect binaries in /bin which link to libraries in /usr/lib,
for the case where the user has /usr on a separate filesystem to /.
However it doesn't scan both image/ and the sysroot, so if a binary in /bin
links to a library in /usr/lib that was built by the same recipe then it will
error out.
This test isn't enabled by default, and because of this serious bug I suspect
nobody else is enabling it either. As /usr being on a separate partition to /
is a very rare configuration these days I think we should delete the test: if
someone cares sufficiently they should write a test that actually works.
