getgrent_next_nss (compat-initgroups): Remove alloca fallback [BZ #18023]
If the caller-supplied buffer is not large enough, fall back directly malloc. The previous __libc_use_alloca check was incorrect because it did not take into account that extend_alloca may fail to merge allocations, so it would underestimate the stack space being used by roughly a factor of two.
