gh-76023: WinFSP giving WinError 1005 fix (Python 3.14.0a3)

[BecoKo]

Make os.path.realpath to ignore WinError 1005 in non-strict mode. (Tested on Python 3.14.0a3 on Windows 11)

Cryptomator issue
python related issue

In cryptomator running WinFSP volume as administrator and make encrypted volumes available to all users, is not recommended.

This is retry of PR#128316 to Python 3.11 . (It seems that this is not a security issue.)

Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

FTR, we usually make PRs against main and then we decide where we will backport them. We don't make PRs (except backports) against a past branch in general (because if there is an issue in an older branch, this issue usually remains...).

Can we add a test?

Can we add a test?

Not trivially - we'd have to (automatically) set up a file system that exhibits this characteristic. But the overall mechanism (non-strict resolution) should be tested well enough.

With the NEWS entry (I suggest Make :meth:`os.path.realpath` ignore Windows error 1005 when in non-strict mode), this is good to go.
