tests/servers: put unix-domain-path inside LOGDIR

Change Unix domain socket paths from `/tmp/curl-socksd-<random>` to
`/drive/path/to/LOGDIR/PIDDIR/*-uds` to avoid having to create and
delete them before use. Also to use a path which remains an absolute one
while passed from MSYS2 Perl to native Windows curl tool and test server
via the command-line, and keep pointing to the same location, fixing:
```
=== Start of file commands.log
../src/curl.exe -q --output log/3/curl1468.out --include --trace-ascii log/3/trace1468
  --trace-time http://this.is.a.host.name:64405/1468
  --proxy socks5h://localhost/tmp/curl-socksd-YnbvRo98 [...]
=== End of file commands.log
=== Start of file socks2_server.log
[...]
14:11:54.597968 Listening on Unix socket D:/a/_temp/msys64/tmp/curl-socksd-YnbvRo98
```
Ref: https://github.com/curl/curl/actions/runs/19896583933/job/57028545111?pr=19812

The curl tool is pending #19825 to fix accepting an absolute unix domain
socket path on Windows.

Assisted-by: Viktor Szakats
Closes #19810
