Initialize `emulated_metadata` fields to avoid uninitialized warnings

Set `emulated_metadata` fields to default values (0) to prevent
potential usage of uninitialized variables in `virtgpu_virgl.c`.
This fix ensures that the compilation doesn't fail due to warnings
being treated as errors when using strict compiler flags.
