crypto: add support for the serpent cipher algorithm
New cipher algorithms 'serpent-128', 'serpent-192' and 'serpent-256' are defined for the Serpent algorithm. The nettle and gcrypt cipher backends are updated to support the new cipher and a test vector added to the cipher test suite. The new algorithm is enabled in the LUKS block encryption driver.
