Description of changes

The pkgconfig requires libcrypto. In the minimal systemdStage1, openssl isn't pulled in by existing dependencies so the probe for libfido2 fails:

$ nix-shell -A systemdStage1

[nix-shell:~/Git/nixpkgs]$ pkg-config --debug libfido2
[...]
Adding 'libfido2' to list of known packages
Searching for 'libfido2' requirement 'libcrypto'
Looking for package 'libcrypto'
Looking for package 'libcrypto-uninstalled'

[nix-shell:~/Git/nixpkgs]$ echo $?
1

So despite being enabled, FIDO2 support isn't actually built at all:

$ nix-build -A systemdStage1
/nix/store/zs5svndbbi0m6iygwnxw0xhn5vynk8jb-systemd-stage-1-250.4

$ ls result/lib/cryptsetup/
libcryptsetup-token-systemd-tpm2.so

After the change:

$ nix-build -A systemdStage1
/nix/store/z1w0qwn5bz16i0qh41sf0ab7nlfgjy1m-systemd-stage-1-250.4

$ ls result/lib/cryptsetup/
libcryptsetup-token-systemd-fido2.so  libcryptsetup-token-systemd-tpm2.so

#179823 is required for TPM2 and FIDO2 support to be actually usable, but I think we can merge this now while that PR is being discussed.
