cmac: some more padding-related tune-ups
...
- use one less temporary buffer
- pedantic: in_len + 15 was a potential overflow
- use a more explicit name instead of 'flag'
- Mn was a bit misleading

cmac: make subkey gen more constant-time

The previous version had secret-dependent memory accesses. While it was
probably not an issue in practice cause the two bytes of the array are
probably on the same cache line anyway, as a matter of principle this should
be avoided.
