[PATCH] readdir_r() is deprecated, use readdir().

[Mark Wielaard <mark@klomp.org>]

Since glibc 2.24 readdir_r() is deprecated.
Applications are recommended to use readdir which is thread-safe when
using different directory streams (we explicitly create a new one here).

	* src/abg-tools-utils.cc (dir_is_empty): Use readdir() instead
	of readdir_r().
