systemd: not buildable without gcrypt
systemd: not buildable without gcrypt

This issue is caused by certain upstream commits such as
91e023d896dd [Move initialize_libgcrypt to separate file].
The result is that systemd requires gcrypt to be enabled and
systemd cannot be simply patched to work without gcrypt
