SELinux labeling with --root/--image needs per-call context to carry an alternate policy database and root prefix. The current LabelOps interface has no way to pass this, forcing any solution to rely on global state. Add a LabelContext *label_context to the label_ops callbacks and all intermediate layers. Generic filesystem functions that most callers use (xopenat_full, write_string_file_full, etc.) get a _label variant carrying the extra parameter, with inline wrappers preserving the original signatures so the vast majority of call sites remain untouched.
