[3.7] bpo-35214: Fix OOB memory access in unicode escape parser (GH-10506) (GH-10522)

Discovered using clang's MemorySanitizer when it ran python3's
test_fstring test_misformed_unicode_character_name.

An msan build will fail by simply executing: ./python -c 'u"\N"'
(cherry picked from commit 746b2d35ea47005054ed774fecaed64fab803d7d)
