[PATCH v4] Add flags option to get xattr method paired to __vfs_getxattr

I will redo the manual audit, perhaps I need to not be so scared of
allconfig build ;-} (currently my runtime & buildtime test platform is
android 4.19 kernel, my bad).
I am going through and exploring/changing/testing everything to deal with
GregKH/jmorris wanting a single xattr_gs_args structure reference where the
flags argument is stowed, rather than YA adding a flags argument. It is
doubling the (mechanical) codebase impact but decreases the future
maintenance and _large_ set of stakeholders (+75 at last count).
