fuse-encfs: workaround netbsd being wrong about which version of FUSE

changed the arguments of fuse_unmount. Fix build.

I get the impression this update was done by someone on NetBSD, so I speculate
the build succeeded to some people. In that cae, bump PKGREVISION, so the
right arguments will be passed!

+Unclear FUSE API mismatch. fuse_unmount as of FUSE 3.0 seems to take
