io: nftw/ftw: Fix stack overflow with large nopenfd [BZ #26353]
The nopenfd value is used as argument for the internal buffer on ftw_statup, which is allocated with alloca and might trigger a stack overflow for large values. This patch replaces the memory allocation to use malloc instead. Checked on x86_64-linux-gnu. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
