Remove the authfile parameter of MakeXRegistryAuthHeader

Having a parameter that modifies the provides types.SystemContext
seems rather unexpected and risky to have around - and the only
user of that is actually a no-op, others only provide a nil
SystemContext; so, remove that option and simplify (well, somewhat;
many callers now have extra &types.SystemContext{AuthFilePath}
boilerplate; at least that's consistent with that code carrying
a TODO to create a larger-scope SystemContext).

Should not change behavior.
