Replace tempdir with tempfile

[alexanderkjall]

as the tempdir crate has been superseded by tempfile.

Now that MSRV was raised in #172 we can replace tempdir with tempfile.

[alexanderkjall]

So this problem seem to be that a sub-dependency of tempdir (that have MSRV 1.63) seem to have a MSRV of 1.65.

As far as I know that isn't really solvable without hand editing a Cargo.lock file, and that seems a bit extreme. If anyone have a suggesion on how to solve this I'm happy to try it out :)

The 1.63 test jobs can be switched to check-only, so our dev dependencies aren't limited by the MSRV.

[alexanderkjall]

I'm not an expert at build jobs, should I delete this line:

https://github.com/rust-lang/glob/blob/master/.github/workflows/rust.yml#L23

since the MSRV build check is done here:

https://github.com/rust-lang/glob/blob/master/.github/workflows/rust.yml#L71

?

[tgross35]

Rather than deleting the first line, just bump it to whatever the MSRV for tempdir / its deps is. No harm in keeping a reasonably old test here, even though we have the MSRV check.

(Would be nice if the MSRV check covered multiple platforms, but that can happen separately)

[alexanderkjall]

Done, I had to dump it all the way up to .71 due to a windows-only dep. Thanks for the guidance.

[tgross35]

Thanks!

Would be nice to get a release with this -- glob is currently the biggest remaining user of tempdir. :)

[tgross35]

It's just a dev dep right? Doesn't hurt to get out of the graph, kicked off #177.
