systemd: break circular dependency with libfido2

libfido2 depends on udev, and when the fido2 feature is enabled
in systemd, systemd depends on libfido2. However, systemd really
only needs libfido2's headers at build time. It uses dlopen to
opportunistically enable the features at runtime. Break this
circular dependency by creating a recipe that provides libfido2's
headers and pkgconfig file. That allows systemd to build with
fido2 enabled and allows libfido2 do build as well.

+Subject: [PATCH] meson: use libfido2_cflags dependency
+
+Add the libfido2 dependency to cryptenroll and cryptsetup's
+meson files. If libfido2's not installed in the default path
+the build wasn't finding its headers correctly.
