[issue25029] MemoryError in test_strptime

Script to reproduce the issue:
---
import time
import locale
import pprint

time_tuple = time.struct_time((1999,3,17,1,44,55,2,76,0))

p1 = time.strftime("%p", time_tuple)
print("current LC_TIME", repr(p1))

locale.setlocale(locale.LC_TIME, ('de_DE', 'UTF8'))
p2 = time.strftime("%p", time_tuple)
print("de_DE (UTF8)", repr(p2))
---

Output:
---
$ python3.4 bug.py
current LC_TIME 'AM'
de_DE (UTF8) ''
---

The problem is that strftime()/wcsftime() *can* return 0, it's not an error. Whereas c31dad22c80d considers that if buflen is 0 but fmtlen is smaller than 5, we must retry with a larger buffer.
