Fixes #27671.

git/git@0c977db made that script
require an extra build step.

Reflex uses hlint in its test suite, failing the build if there are
any lint warnings. hlint depends on a newer haskell-src-exts than the
rest of the nixpkgs haskell infrastructure, so this avoids reflex
dependening on multiple versions of haskell-src-exts, which would
otherwise abort the build.

Otherwise git2r builds a bundled libgit2

rPackages.git2r: Use system libgit2

haskell.compiler.ghcHEAD: 20190115 -> 20190601

haskellPackages.reflex: dontCheck

git: 2.21.0 -> 2.22.0

git: build diff-highlight if Perl support is enabled

opencascade: build with vtk and freeimage, patch for fontconfig support

Fixes the broken metrics evaluation which was caused by a `trace`
warning in stdout which confused `jq` in `pkgs/top-level/metrics.nix`.

Also made the `bind-device` feature optional as suggested after the
merge.

Do not set FUSERMOUNT_DIR since we already set it though
NIX_CFLAGS_COMPILE.

Setting it twice results in a lot of warnings like this one:

<command-line>:0:0: warning: "FUSERMOUNT_DIR" redefined

which makes the build look potentially broken.
This doesn't affect the result but fuse3 will now build without any
warnings and building fuse yields less warnings.
