Shuvam Pandey f13f1b0cb5 seq_buf: export seq_buf_putmem_hex() and add KUnit tests ...

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.
