PR27413: use bsdtar to unpack deb-related formats
dpkg-deb has been reported to be fragile when running under
debuginfod, whereas bsdtar (libarchive) is happy with all these
flavors of files. Switch to a bsdtar based pipeline, now
equipped with an escaped glob pattern that adapts to a variety
of interior data.tar* compression formats.
No testsuite impact. .ipk format tested with some random openwrt and
kino-extension binaries found on the net. Some of these are built
with out buildid, and hardly any with debuginfo, but whatever, bsdtar
and elfutils extract whatever info is there.
