elfutils: security bump to version 0.174

Fixes the following security issues:

CVE-2018-16062: dwarf_getaranges in dwarf_getaranges.c in libdw in elfutils
before 2018-08-18 allows remote attackers to cause a denial of service
(heap-based buffer over-read) via a crafted file.

CVE-2018-16402: libelf/elf_end.c in elfutils 0.173 allows remote attackers
to cause a denial of service (double free and application crash) or possibly
have unspecified other impact because it tries to decompress twice.

CVE-2018-16403: libdw in elfutils 0.173 checks the end of the attributes
list incorrectly in dwarf_getabbrev in dwarf_getabbrev.c and dwarf_hasattr
in dwarf_hasattr.c, leading to a heap-based buffer over-read and an
application crash.
