sys/linux: improve AF_ALG alg name generation

There is effectively infinite number of possible crypto
algorithm names due to templates. Plus there is tricky
relation between algorithms and algorithm type names.

This change adds custom mutator for sockaddr_alg struct
to improve variance in generated algorithms.
