libdevmapper: Support dm-crypt integrity_key_size option

Browse Source 
This patch implement support for setting specific integrity key size
option in dm-crypt, available since dm-crypt version 1.28.0.

This can be used for setting non-standard HMAC key length.

Mostly based on code from Ingo Franzki <ifranzki@linux.ibm.com>
