testsuite: temporary drop cross compilation test, remove binaries

The idea behind the test is that modinfo should work with foreign
modules - be that CPU architecture, endianess, bit width or otherwise.

On the other hand, having binary modules baked into the repo isn't great
since they can may be outdated wrt their in-tree source code, may
trigger warnings by various tools (the Debian linter flags them as
"source-not-available") and in general it's better if they're actually
generated via the in-tree Makefile.arch file.

Remove the binaries and temporarily drop the tests. We'll add proper
cross-compilation and re-enable them at a later stage.
