+libcgroup-internal.h: reorder the header stacking.
+
+`man 3 fts` not only specifies the headers to be included, but
+also the order.  <fts.h> must be included after <sys/types.h>
+and <sys/stats.h>.  On glibc and uClibc systems, an incorrect
+order does not pose a problem, but on musl this leads to undefine
+types such as dev_t and friends.
