[WINESYNC] Allow using the "new" Wine-Staging patchinstall.py script.

Wine-Staging switched to staging/patchinstall.py , removing the
deprecated patches/patchinstall.sh in Feb.16, 2023 commit
wine-staging/wine-staging@c1b4af9
just before the v8.2 release.

In order to maintain interoperability between older and newer
Wine-Staging versions, try to run first the new script; if it fails,
fall back to the older script.
