System shared-library dependencies are not lazily loaded in single-file on Linux

[agocke]

See #45720 for an example.

It looks like the default runtime deployment avoids this by loading libSystem.Net.Security.Native.so lazily, which will only then load many of the system libraries. Since that library is not statically compiled into the host, its dependencies are loaded eagerly.

Unfortunately the only way to implement this may be to call dlopen ourselves, since I don't know a way of getting the Linux linker to automatically insert the stub.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

This should be fixed in #55037
