Update comment for the copy_file_range operation (#497)

copy_file_range was first implemented with copy-based emulation in
glibc 2.27, but the emulation was subsequently removed again because
correct emulation depends on why the application attempted to make a
copy.  Therefore, file systems cannot rely on low-level userspace
performing emulation.
