spi: spidev_test: Improve decoded text part of hex dump
- Print spaces as spaces,
- Do not print characters > 126, as they will be shown as garbage
in the modern UTF-8 era,
- Use a normal period instead of its hexadecimal ASCII value,
- Delimit the text part with pipe symbols on both sides (was left side
only), without any spaces, to make it clear where the decoded text
starts and ends,
- Drop a useless comment.
