Add identifier for PBKDF2 with AES-CMAC-PRF-128

Browse source 
This algorithm is used for example by the Thread 1.1.1 specification,
which is not public but can be obtained free of charge at
https://www.threadgroup.org/ThreadSpec

Here it doesn't really make sense to define a parametrised family, as
this really seems to be the only use of PBKDF2 with a CMAC-based PRF (or
with any PRF other than HMAC with SHA1 or SHA2, for that matter).
