Since GHC is a cross compiler, it's perfectly possible to make haskell
binaries on platforms without GHCs. `windows ++ unix` seems good enough
for now.
Also don't default `hydraPlatforms` to `platforms`. The former must be a
list of systems (strings), but the latter is a list of systems or
patterns.
Otherwise obscure cross-compilations are hampered. `all` breaks all but
the initial derivation (which we can't even write yet) in an open world
setting however, so we really shouldn't have it.
Djblets is unmaintained: has not been updated since 2015, but had many releases.
Dependency django_pipeline_1_3 is broken and should anyway be removed from pythonPackages because we want to have a consistent package set.
Because the reviewboard package also hasn't been updated since 2015 and depends on djblets, it is removed as well.

This changes the emscripten package so that it specifies the rev from
the binaryen repo to use, and sets it to always use the version that has
been tagged for use with that version of emscripten. This should force
future updates of emscripten to also update binaryen.
Binaryen can also be installed as a stand-alone package, so there's some
logic added to the binaryen package to allow building in both ways, and
distinguishing between them.
