wipefs: print all signature permutations
The same FS/RAID/PT signature may be detected by more ways and on more
places on the device. The libblkid returns only the first detected
signature by default. This patch use blkid_probe_hide_range() to
re-scan device for all possible permutations of the same signature.
For example the default wipefs(8) output as well as --no-act output will
contains primary as well as backup GPT signature now.
