Use architecture libdir.

Instead of always using /usr/lib/mandos, use whatever the architecture
specifies, like /usr/lib/x86_64-linux-gnu/mandos or /usr/lib64/mandos.
Still use /usr/lib/mandos as a fallback.

* Makefile (LIBDIR): New.
 (install-client-nokey, uninstall-client): Use LIBDIR instead of
                                           $(PREFIX)/lib.
* initramfs-tools-hook: Detect correct libdir and copy from there.
