Update sysutils/kio-fuse to latest upstream release

kio-fuse does some FUSE magic to pass remote KIO paths (e.g. when
browsing SMB or ftp from Dolphin) to non-KIO-aware applications
(e.g. opening a text file with vi). This 5.0.0 release has been
out for a while and is functionally equivalent to the previous
one; now, however, there's real release tarballs and everything.

Existing patches have been re-built for this release and then
submitted upstream, which is why they now have git-hashes.
