Andreas Rheinhardt f49375f28f avutil/aes: Don't use out-of-bounds index ...

Up until now, av_aes_init() uses a->round_key[0].u8 + t
as dst of memcpy where it is intended for t to greater
than 16 (u8 is an uint8_t[16]); given that round_key itself
is an array, it is actually intended for the dst to be
in a latter round_key member. To do this properly,
just cast a->round_key to unsigned char*.

This fixes the srtp, aes, aes_ctr, mov-3elist-encrypted,
mov-frag-encrypted and mov-tenc-only-encrypted
FATE-tests with (Clang-)UBSan.
