tests: fill in the Windows pattern for `$EADDRNOTAVAIL$` matching This fixes test-https.t on Windows. It looks like the real error translation is "Cannot assign requested address.", and the message here is the start of a longer description, so I'm not sure why this part is emitted. But it's not worth digging into, as it's evidently the same failure.

tests: avoid a cascading failure on Windows The `identify --debug` command here on Windows emits skip updating dirstate: identity mismatch because of the debug switch, which got captured and added to `.hgtags`, and then hijinx ensued. The point of `--debug` seemed to be to get the long hash, so just do that with templating. I have not idea if the message is indicating a problem- there seems to be many more of them in other tests that are not present on Linux.
