mksquashfs: pass reader_buffer to write_file_empty()

Make the behaviour of write_file_empty() match the
other write_file_*() functions, where it deletes the
reader_buffer.

This removes the messy special handling of write_file_empty()
in write_file() where it has to delete the reader_buffer
but only for write_file_empty().
