Mikulas Patocka fb4079aa4d cryptsetup: add support for the "fix_padding" option ...

This patch adds support for fixed padding to cryptsetup.

* Cryptsetup will accept superblocks version 4.
* If the dm-integrity target version is greater than 1.4, cryptsetup will
  add a flag "fix_padding" to the dm-integrity target arguments.

There is still one quirk: if we have an old libdm without
DM_DEVICE_GET_TARGET_VERSION and if dm-integrity module is not loaded,
cryptsetup will not detect that it can use the "fix_padding" option.
