a84db18fc7 tar,unzip: postpone creation of symlinks with "suspicious" targets
This mostly reverts commit bc9bbeb2b8
"libarchive: do not extract unsafe symlinks unless $EXTRACT_UNSAFE_SYMLINKS=1"

Users report that it is somewhat too restrictive. See
https://bugs.busybox.net/show_bug.cgi?id=8411

In particular, this interferes with unpacking of busybox-based
filesystems with links like "sbin/applet" -> "../bin/busybox".

The change is made smaller by deleting ARCHIVE_EXTRACT_QUIET flag -
it is unused since 2010, and removing conditionals on it
allows commonalizing some error message codes.

ecaec1dbec testsuite: update busybox and bzcat tests
Test scripts that use CONFIG_* variables need to source .config.
Since this wasn't being done for busybox many tests were skipped.
As a result new failures due to changes in help output were missed.

Also remove some unnecessary echos in the bzcat script.

2598915d43 gunzip: fix from gzip-1.3.12 for gzip file with all zero length codes
Corresponding changelog from gzip-1.3.12 reads:

"""
2006-12-20  Paul Eggert  <eggert@cs.ucla.edu>
        * inflate.c (huft_build): Fix regression that caused gzip to
        refuse to uncompress null input (all zero length codes).  Problem
        reported by Yiorgos Adamopoulos.  This regression was caused by
        the security patch installed 2006-11-20, which in turn came from
        Debian, which in turn apparently came from Thomas Biege of SuSe.
