Alan Somers 1ea95ba231 cp: fall back to read/write if copy_file_range fails 
Even though copy_file_range has a file-system agnostic version, it still
fails on devfs (perhaps because the file descriptor is non-seekable?) In
that case, fallback to old-fashioned read/write. Fixes
"cp /dev/null /tmp/null"
