Improve port to NetBSD tzalloc

Browse source 
Problem reported by Valery Ushakov (Bug#30738#13).
* src/editfns.c (tzlookup) [__NetBSD_Version__ < 700000000]:
If tzalloc fails for any reason other than memory exhaustion,
assume it’s because NetBSD 6 does not support tzalloc on
POSIX-format TZ strings, and fall back on tzdb if possible.
