[illink] Ensure we replace the dotnet SDK path in the _ExtraTrimmerAr…

…gs for remote builds (#16294)

From net7, the original ILLInk targets are adding a new link attribute pointing to a supressions file inside the ILLink tasks folder, e.g: '--link-attributes "C:\Program Files\dotnet\sdk\7.0.100-rc.2.22477.23\Sdks\Microsoft.NET.ILLink.Tasks\build\6.0_suppressions.xml"'.

For remote builds, we need to replace the original dotnet folder with the XMA dotnet folder in the Mac, so in our override targets we replace this value before passing it to the ILLink task
