2a053a2430 ar: read_num(): fix reading fields using the entire width
ar fields are fixed length text strings (padded with spaces). Ensure
bb_strtou doesn't read past the field in case the full width is used.

The fields are only read once, so the simplest/smallest solution to me
seems to be to just pass the length to read_num() and then zero terminate
the string before passing it to bb_strtou. This does mean that the fields
MUST be read in reverse order, so some minor reshuffling was needed.

Bloat-o-meter:
function                                             old     new   delta
get_header_ar                                        394     414     +20
read_num                                              29      36      +7
