Update crypto-mac to 0.11 in blake2

[Eijebong]

Trying to cleanup a dependency tree where we have 3 versions of crypto-mac, one of them from blake2. Would be nice if you could update it.

I tried doing it myself but can't figure out why tests are broken. Here's the diff:

crypto-mac functionality will be merged into digest v0.10, so this issue will be fixed in the next blake2 release, see #217.

The tests are failing because storage format of test vectors has changed a bit between crypto-mac v0.10 and v0.11
