package/cryptsetup: fix tmpfiles.d setup

The configure script uses pkg-config to detect the location of
tmpfiles.d but imposes an unspecified ordering dependency with systemd.
Instead of relying on systemd being built before cryptsetup, set the
directory path explcitly, and ensure it is not set when systemd-tmpfiles
is disabled.
