libminc: 2.4.03 -> unstable-2020-07-17

[bcdarwin]

and update reverse dependencies accordingly

Motivation for this change

• update libminc; most importantly a fix for a scaling bug (miconvert_voxel_to_real: Ignore scaling for float volumes BIC-MNI/libminc#109)
• libminc builds against default hdf5, so drop hdf5_1_8 from tree
• the location of CMake files has changed, so the builds of its reverse dependencies need to be updated

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.

Getting some weird resource temporarily unavailable test failures on nix.ci but nixpkgs-review pr succeeds locally; probably some OfBorg resource limit?

Rebased onto master and resolved breakage from another PR (#91071).

[lheckemann]

Wow, upstream could do with some more releases :D

That aside, LGTM.

[lheckemann]

That is indeed an, uh, interesting failure on ofborg. Let's just kick it.

[bcdarwin]

libminc tests are still weirdly failing, so I've disabled parallel building -- perhaps that will help.

[bcdarwin]

@lheckemann turns out the tests can't be run in parallel (and enableParallelBuilding doesn't control ctest); see BIC-MNI/libminc#110. Anyway, good to go now.
