Fix ucred for illumos/solaris

[papertigers]

Fixes an incorrect import.

In order to run the test suite successfully on illumos I had to modify

• generator-rs => Add support for illumos/solaris Xudong-Huang/generator-rs#16
• mio-uds => Not yet fixed (we don't appear to have a way to set FIOCLEX on the fds in question)

However, once I patched those via [patchs.crates-io] in the workspace the test suite runs to completion with:

test result: ok. 129 passed; 0 failed; 1 ignored; 0 measured; 0 filtered out

The PR for the mio-uds fix is at deprecrated/mio-uds/pull/26

Bump.
Bummer this missed the tokio 0.2.0 release.

Do you have any thoughts on how to get illumos / solaris CI?

[papertigers]

I don't because azure pipelines and other's only seem to offer mostly windows/linux VMs. We use jenkins internally for illumos CI.

One of the main gaps we are trying to close right now is getting an official illumos rust target so that we can also get rustup in the process.

Doesn’t azure support bringing your own hardware? If so, could we integrate a Solaris box in the process somehow?

[papertigers]

@carllerche for azure pipelines? When I looked at the docs it seemed that they only offered a few specific VM flavors. Do they support bringing your own hardware? I am interested in figuring out how we can get to a CI solution in general for illumos, but can't speak much for the solaris side of things.
