[PATCH] test-lib: stricter unzip(1) check

On FreeBSD 10.3 (but presumably any FreeBSD 8+), /usr/bin/unzip
exists, but is insufficient for t5003 due to its non-standard
handling of the -a option[1].  This version of unzip exits
with "1" when given the "-v" flag.

However, the common Info-ZIP version may be installed at
/usr/local/bin/unzip (via "pkg install unzip") to pass t5003.
This Info-ZIP version exits with "0" when given "-v",
so limit the prereq to only versions which return 0 on "-v".
