[LTP] [PATCH v2 05/15] ujson: reader: Return UTF-8 length when !str

[Andrea Cervesato]

From: Andrea Cervesato <andrea.cervesato@suse.com>

When parse_ucode_esc() is called without an output buffer to calculate
string length, it returned the unicode code point instead of the UTF-8
byte length. This vastly overestimated the required buffer size. Return
the UTF-8 byte length instead.

Fixes: c50a0e0751c8 ("libs: Vendor ujson library")
