shell-recorder: Avoid a crash when the cursor texture is NULL

When running as a wayland compositor, MetaCursorTracker might
legitimately not have a displayed cursor because e.g. a client unsets
the cursor surface.

Note that, under an X session, the assumption that the tracker always
has a cursor texture is true because XFixesGetCursorImage() always
returns data even if the cursor isn't visible.
