Remove libfreetype.so from adoptopenjdk's derivation.

[tomfitzhenry]

Motivation for this change

This caused some reverse dependencies of adoptopenjdk to depend on
adoptopenjdk's libfreetype, rather than the NixOS
libfreetype. For example: #57733

Now the derivation does not contain libfreetype.so . The JRE links to
nixpkg's freetype:

$ ldd /nix/store/9iyxm1nkn35xhjgri041r980z4p5ls5g-adoptopenjdk-hotspot-bin-11.0.2/lib/libfontmanager.so | grep -i freetype
	libfreetype.so => /nix/store/ycbkq39cngzx19j829qzgdnw3mx3z78g-freetype-2.9.1/lib/libfreetype.so (0x0000795e30702000)

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
• 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 nox --run "nox-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)
• Assured whether relevant documentation is up to date
• Fits CONTRIBUTING.md.

I'm unfamiliar with Nixos policy on which is preferable:
(i) force adoptopenjdk to depend on the NixOS freetype
(ii) allow adoptopenjdk to depend on its own freetype, but do not expose that to adoptopenjdk's reverse dependencies

This PR implements (i).

[tomfitzhenry]

I think (ii) is a better solution because it means we aren't overriding adoptopenjdk's dependencies.

Looks like (ii) could be done via https://nixos.org/nixpkgs/manual/#chap-multiple-output .

[tomfitzhenry]

(i) seems to be the NixOS solution: use NixOS packages where possible.

So I'll leave this PR as it is. This changes the JRE to use NixOS's libfreetype, and hence benefit from libfreetype security updates. This fixes #57733 too.

A separate PR can split the JRE's shared libraries to a separate libs package, which will prevent similar issues from re-occurring.

Closure size has dropped, as expected (since libfreetype.so has been removed):
