Log Message:
Make npplayer search default pkgsrc dirs.

Now npplayer works without MOZ_PLUGIN_PATH env as
/usr/pkg/lib/nspluginwrapper/i386/netbsd/npplayer \
 src=https://helpx.adobe.com/content/dam/help/en/flash-player/assets/flash_tree.swf
etc.

Bump PKGREVISION.

XXX: probably we should move the default dir for adobe-flash-plugins11
     from historical ${PREFIX}/lib/netscape to ${PREFIX}/lib/mozilla
