[RFC PATCH 6/7] t5004: use GNU tar to avoid known issues with BSD tar

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

56ee96572a ("t5004: resurrect original empty tar archive test", 2013-05-09)
added a test to try to detect and workaround issues with the standard tar
from BSD, but at least in NetBSD would be better to instead require GNU tar
which is available from pkgsrc
