Update opam

[constfun]

Since the changes from @jendas1 were merged we should probably allow opam to install ocamlfuse on mac.

As published, opam install ocamlfuse fails with platform check.
With this change opam pin installs the package fine.

Yes, the problem is that opam needs also the correct depexts entry for osx. If you know the name of the FUSE package in homebrew, I could add a line like: [["osx" "homebrew"] ["fuse-package-name"]]. This way the CI system used by the opam repository should be able to compile it and the package could be accepted.

Good idea and better now than never, so here it goes:

I originally installed the binary distribution from https://osxfuse.github.io and that works.

The FUSE for macOS includes a "Preference Panel" that shows up in system preferences. This (ie. a package bundled with a GUI) generally means that the package would be in the cask tap for homebrew.

I've added the fully qualified name to the required cask to the opam file as you've suggested:

• If the user has caskroom tapped, running opam depext ocamlfuse will install the required dependency and ocamlfuse can be compiled.
• If the user doesn't have caskroom tapped (a likely scenario) opam is actually smart enough to tap the cask and only then install the dependency. Great!

Tested with a local pin first with -n to run opam depext without installing, and then a simple opam install ocamlfuse to make sure that it compiles.

It worked! This is the PR to the official repository. Thanks again!
