MDEV-23187: Assorted assertion failures in json_find_path with certain

Fix by Alexey Botchkov

The 'value_len' is calculated wrong for the multibyte charsets. In the
read_strn() function we get the length of the string with the final ' " '
character. So have to subtract it's length from the value_len. And the
length of '1' isn't correct for the ucs2 charset (must be 2).
