tests/snprintb: clean up comments

libutil/snprintb: allow 'f' to be combined with ':'

But only if the numeric value can be clearly distinguished from the
description. This style is used by sh3/dmacreg.h.
tests/snprintb: test for out-of-memory writes

In 2024, snprintb_m did that in a few scenarios.
tests/snprintb: ensure that the value has power-of-two digits

In direct calls to h_snprintb_m_len, several arguments are integers, so
provide a way to distinguish them visually by forcing the value to be
given in hexadecimal. The buffer sizes are typically given in decimal.

Prevent excess or forgotten digits by requiring the number of digits in
the value to be a power of two.
snprintb: allow 'F' and 'f' to be freely mixed with '=' and ':'

This restores the behavior from NetBSD 10.

While in most cases, 'f' is used with '=' and 'F' is used with ':',
there are useful cases for the other combinations as well, so allow
them.
