Adhemerval Zanella 0b3503e2e1 locale: Use correct buffer size for utf8_sequence_error [BZ #19444] 
The buffer used by snprintf might not be large enough for all possible
inputs, as indicated by gcc with -O1:

../locale/programs/linereader.c: In function ‘utf8_sequence_error’:
../locale/programs/linereader.c:713:58: error: ‘%02x’ directive output
may be truncated writing between 2 and 8 bytes into a region of size
between 1 and 13 [-Werror=format-truncation=]
  713 |     snprintf (buf, sizeof (buf), "0x%02x 0x%02x 0x%02x 0x%02x",
      |                                                          ^~~~
../locale/programs/linereader.c:713:34: note: directive argument in the
range [0, 2147483647]
  713 |     snprintf (buf, sizeof (buf), "0x%02x 0x%02x 0x%02x 0x%02x",
      |                                  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../locale/programs/linereader.c:713:5: note: ‘snprintf’ output between
20 and 38 bytes into a destination of size 30
  713 |     snprintf (buf, sizeof (buf), "0x%02x 0x%02x 0x%02x 0x%02x",
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  714 |               ch1, ch2, ch3, ch4);
