package/elfutils: security bump to version 0.176

Fixes CVE-2018-18310: An invalid memory address dereference was
discovered in dwfl_segment_report_module.c in libdwfl in elfutils
through v0.174. The vulnerability allows attackers to cause a denial of
service (application crash) with a crafted ELF file, as demonstrated by
consider_notes.

Fixes CVE-2018-18520: An Invalid Memory Address Dereference exists in
the function elf_end in libelf in elfutils through v0.174. Although
eu-size is intended to support ar files inside ar files,
handle_ar in size.c closes the outer ar file before handling all inner
entries. The vulnerability allows attackers to cause a denial of service
(application crash) with a crafted ELF file.

Fixes CVE-2018-18521: Divide-by-zero vulnerabilities in the function
arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers
to cause a denial of service (application crash) with a crafted ELF
file, as demonstrated by eu-ranlib, because a zero sh_entsize is
mishandled.
