misc-utils/wipefs.c: In --all mode, wipe several times until no further
signatures are found. This is required for file systems like VFAT which
can be detected in multiple different ways. This is fixed properly in 2.21
(see LP #1012081), but does not backport well, so use this local hack for
now. (LP: #1046665)
