runtests: fix SSH server not starting in cases, re-ignore failing vcpkg CI jobs

Replace `Cwd::abs_path()` with `File::Spec->rel2abs()`. The former
requires the file to exist, but in some cases, it's missing.

Seen in MSVC vcpkg jobs using Chocolatey OpenSSH v8.0.0.1 ending up with
`$path=/d/a/curl/curl/bld/tests/log/3/server/ssh_server.pid`, which does
not exist while converting to an absolute path (the path is already
absolute, but the conversion is done unconditionally):
```
Use of uninitialized value in subroutine entry at D:/a/curl/curl/tests/pathhelp.pm line 128.
can't convert empty path at D:/a/curl/curl/tests/pathhelp.pm line 128.
```

Ref: https://github.com/curl/curl/actions/runs/13751862952/job/38453816737#step:14:3185 (trace)

Also ignore 3 new libssh2 jobs failing due to memleak.

Partial revert of 1bd5ac998bbc943dbf812b2824ad0f532201734c #16570

Closes #16636
