tty, proc, kernfs, random: Use copy_splice_read()
Use copy_splice_read() for tty, procfs, kernfs and random files rather
than going through generic_file_splice_read() as they just copy the file
into the output buffer and don't splice pages. This avoids the need for
them to have a ->read_folio() to satisfy filemap_splice_read().
