Wipe luks2 headers after lvcreate

[smoser]

Wipe luks2 headers after lvcreate.

Versions of libblkid, before 2.33 would not completely wipe luks 2 headers. After we create a thick LV, wipe any remaining headers ourselves.

This should not be that big of a problem, but when it was mixed with a liberal running of 'cryptsetup luksUUID' after LV creation things went awry. cryptsetup will automatically repair a broken header that it finds, and it would find such a header because lvm did not completely wipe it. To be clear, 'cryptsetup luksUUID' is not a read-only operation.

Also complicating things was the fact that we were creating luks 2 volumes and then running with an old LVM.

2 other changes snuck in here:

• Update to newer lint. v1.47.2 to support golang 1.18
• Fix a Makefile error resulting in 'bad substitution'
