Update RustCrypto dependencies

[tarcieri]

Updates the following RustCrypto dependencies to the latest versions:

• aes-gcm v0.9.0
• hmac v0.11.0
• hkdf v0.11.0

[tarcieri]

Heads up: the RUSTEC-2021-0059 and RUSTSEC-2021-0060 unmaintained crate advisories will likely apply to current users of cookie-rs until these dependencies are updated, in case you start getting reports.

Thank you for keeping the libs updates. I really appreciate your effort here.

Merged in 14b053a.

@tarcieri It looks like aes has a new MSRV. Previously, it compiled just fine on 1.41. Now, I'm getting the following:

error[E0658]: unions with non-`Copy` fields are unstable
   --> aes-0.7.0/src/autodetect.rs:30:13
    |
30  | /             pub(super) union Inner {

    = note: for more information, see https://github.com/rust-lang/rust/issues/55149

Any chance MSRV could be pushed back to 1.41?

@SergioBenitez with the force-soft feature, the MSRV of the aes crate is still 1.41+.

I now realize there's no corresponding force-soft feature for the aes-gcm crate itself though. I could potentially add that if you'd like to keep MSRV at 1.41.

While it's debatable whether MSRV should be part of semver or not, I'd like to be conservative here and not break MSRV in a minor point release, so this would be ideal.
