Fix the package list: Over the last couple of snapshots, a number of
components has moved from the Wine Staging project into Wine proper,
so %%STAGING%%foo/bar/smthng in pkg-plist now becomes just foo/bar/smthng.

However, make check-plist did not notice this and indeed both the
port before this update and with this update always pass check-plist
without issues, both when the STAGING option is set and when it's not.

(This is not a cosmetic issue, by the way, it did affect functionality
of the Wine ports.)
