Fix FreeBSD build break

It took until this patch for me to check the runtime.freebsd-x64.Microsoft.DotNet.ILCompiler* nugets generated from crossbuilds.

It turns out they were all linux ELFs. Nothing appears to have consumed it so when building natively so it was uncaught. shrug

We don't use the contents of the package as part of the repo build. The packages are smoke tested in the dotnet/sdk repo unit tests. If you wanted to test the built packages locally, you'd need to use https://github.com/dotnet/runtime/blob/main/docs/workflow/building/coreclr/nativeaot.md#building-packages this workflow ("Building packages").

It was fine before b8e0ce0 right? FreeBSD and other OS were disabled before last week, now we are only disabling FreeBSD and it is still breaking the others. We should bring back the original condition or use this one:

runtime/src/installer/pkg/sfx/Microsoft.NETCore.App/Microsoft.NETCore.App.Crossgen2.sfxproj

Lines 21 to 22 in 0105386

	<!-- Publish crossgen2 as a single-file app on native-OS builds. Cross-OS NativeAOT compilation is not supported yet -->
	<NativeAotSupported Condition="'$(CrossBuild)' == 'true' and '$(TargetOS)' != '$(HostOS)'">false</NativeAotSupported>

Just checked:
runtime.freebsd-x64.Microsoft.DotNet.ILCompiler.8.0.0-preview.3.23174.8 and runtime.freebsd-x64.Microsoft.DotNet.ILCompiler.8.0.0-preview.4.23259.5 both contain Linux ELFs. They were crossbuild from tags/PREVIEWNUM from dotnet/runtime.
It was building before b8e0ce0 but it appears it was always generating the wrong package for ILCompiler. Other packages like Crossgen2 and ILAsm have FreeBSD ELFs in them.
