emulators/fceux: Update to 2.6.5
An interim release, gathering bug fixes and improvements from the past
- move REINPLACE_CMD usage to pre-configure to make make makepatch easier to use.
- commit 2d34c2b for PR #262886 has changed the package list to ship a man page we explicitly did not want to ship. Fix the post-install target and pkg-plist to continue not shipping the man page.
