cpio: fix CVE-2016-2037

"The cpio_safer_name_suffix function in util.c in cpio 2.11 allows
remote attackers to cause a denial of service (out-of-bounds write)
via a crafted cpio file."

Note that there appear to be two versions of this fix. The original
patch posted to the bug-cpio mailing list [1] is used by Debian [2],
but apparently causes regression [3]. The patch accepted to the
upstream git repo [4] seems to be the most complete fix.
