Log:
  Add @generated tag to libc syscall asm wrappers
  
  Although libc syscall wrappers do not get checked in this can aid in
  finding the source of generated files when spelunking in the objdir.
  
  Multiple tools use @generated to identify generated files (for example,
  in a review Phabricator will by default hide diffs in generated files).
  For consistency use the @generated tag in makesyscalls.sh as we've done
  for other generated files, even though these wrappers aren't checked in
  to the tree.
