Xiaoming Ni 106ff08526 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.
