Fix hardened-binaries test for .NET 9

[omajid]

With .NET 9, the NativeAOT feature results in the inclusion of a few .o (object) files in the SDK. The file reports those as:

/usr/lib64/dotnet/.../libbootstrapper.o: ELF 64-bit LSB...

Which means the test then tries to check if it was linked with BIND_NOW and GNU_RELRO. That doesn't make any sense, because this isn't a shared library or an executable that the linker has run over.

Fix that by skipping testing any .o files.

Thanks for looking into this @omajid!

It would be nice if this test would be explicit about what expectation isn't met for a certain file. Currently, the output is the matches (passes), which makes it unclear what the failing condition is.

This was the output for the failure:

We could just add set -x to do this.
