Add corruption failure option to zinject(8)

Browse Source 
Added a 'corrupt' error option that will flip a bit in the data
after a read operation.  This is useful for generating checksum
errors at the device layer (in a mirror config for example). It
is also used to validate the diagnosis of checksum errors from
the zfs diagnosis engine.
