Avoid null pointer dereference crash after OOM in Snowball stemmers.

Browse Source 
Absorb upstream bug fix (their commit
e322673a841d9abd69994ae8cd20e191090b6ef4), which prevents a null
pointer dereference crash if SN_create_env() gets a malloc failure
at just the wrong point.

Thanks to Maksim Korotkov for discovering the null-pointer
bug and submitting the fix to upstream snowball.
