Disable native strndup and strnlen on AIX.
On at least some revisions of AIX, strndup returns unterminated strings under some conditions, apparently because strnlen returns incorrect values in those cases. Disable both on AIX and use the replacements from openbsd-compat. Fixes problem with ECDSA keys there, ok djm.
