The seq_buf KUnit suite does not exercise seq_buf_putmem_hex().
Add one test for the len > 8 chunking path and one overflow test
where a later chunk no longer fits in the buffer.
Export seq_buf_putmem_hex() as well so SEQ_BUF_KUNIT_TEST=m links
cleanly. Without the export, modpost reports seq_buf_putmem_hex as
undefined when seq_buf_kunit is built as a module.
