RUSTSEC-2021-0059: aesni has been merged into the aes crate

[github-actions]

aesni has been merged into the aes crate

Details
Status	unmaintained
Package	aesni
Version	0.6.0
URL	RustCrypto/block-ciphers#200
Date	2021-04-29

Please use the aes crate going forward. The new repository location is at:

<https://github.com/RustCrypto/block-ciphers/tree/master/aes>

AES-NI is now autodetected at runtime on i686/x86-64 platforms.
If AES-NI is not present, the aes crate will fallback to a constant-time
portable software implementation.

To prevent this fallback (and have absence of AES-NI result in an illegal
instruction crash instead), continue to pass the same RUSTFLAGS which were
previously required for the aesni crate to compile:

RUSTFLAGS=-Ctarget-feature=+aes,+ssse3

See advisory page for additional details.
