windows: degrade to py2 behavior when reading a non-symlink as a symlink

While waiting for the push to hg-committed in WSL to complete, I ran a
`phabimport` from Windows and got this traceback:

    $ hg phabimport 11313
    ** Unknown exception encountered with possibly-broken third-party extension "mercurial_keyring" (version N/A)
    ** which supports versions unknown of Mercurial.

    ValueError: not a symbolic link

Both exceptions look accurate (the file exists, and the Windows side can't read
WSL side symlinks).  I didn't try to reproduce this entirely within the Windows
side, but we can do better than a cryptic stacktrace.  With this change, the
same scenario results in this abort:

    abort: C:\Users\Matt\hg/.hg/store/lock: The file cannot be accessed by the system

When both the `push` and `phabimport` are done on the Windows side, it prints a
message about waiting for the lock, and successfully applies the patch after the
push completes.

I'm not sure if there's enough info to be able to convert the abort into the
wait scenario.  As it stands now, we don't support symlinks on Windows, which
requires either a UAC Administrator level process or an opt-in in developer
mode, and there are several places where the new symlink on Windows support in
py3 was explicitly disabled in order to get tests to pass quicker.

Test signal-safe-lock in web and non-web processes

 by default, signal interrupt should be disabled while making a lock file

  $ hg debuglock -s --config extensions.disablesig=disablesig.py
  abort: SIGTERM cannot be replaced
  [255]

 but in hgweb, it isn't disabled since some WSGI servers complains about
 unsupported signal.signal() calls (see issue5889)

  $ cat hg.pid >> $DAEMON_PIDS

  $ hg clone -q http://localhost:$HGPORT/ repo
  $ hg bookmark -R repo foo

 push would fail if signal.signal() were called
